Sweaters and knitwear guide
How to choose and wear a women’s Sweater or gilet: the Hello Moon guide
Lightweight Sweater, chunky knit, oversized Sweater, cardigan, or buttoned gilet: knitwear lets you play with volumes, materials, and layering all year round.
To choose the right women’s Sweater or gilet, focus mainly on its cut, neckline, composition, and the thickness of its knit. These elements affect how it drapes, its comfort, its warmth, and how you can wear it with the other pieces in your wardrobe.
In this guide, Hello Moon helps you understand the different types of Sweaters and gilets, choose your knitwear, and style it according to your personal style and the season.

What is the difference between a Sweater, a gilet, and a cardigan?
- A Sweater is generally closed at the front and pulled on over the head.
- A gilet opens at the front and can be buttoned or worn open, depending on its construction.
- The term cardigan generally refers to a knitted gilet that is open at the front, often with buttons.
These pieces all belong to the knitwear family, but they are not used in exactly the same way. The Sweater often forms a complete layer, while the gilet and cardigan offer more ways to play with layering.
How do you choose the right women’s Sweater?
When choosing a Sweater, start by looking at its cut and the desired volume.
A relatively fitted Sweater slips easily under a jacket or blazer. A straight-cut Sweater offers more room, while an oversized Sweater intentionally creates more volume.
Next, look at the neckline, the thickness of the knit, and especially its composition. These elements largely determine how the Sweater drapes, its comfort, and how you can layer it.
What are the different types of women’s Sweaters?
What is a lightweight Sweater?
The lightweight Sweater has a relatively light, low-volume knit.
It can be worn alone or used as a layer under a blazer, jacket, or coat.
Its lightweight volume makes it particularly well suited to layering and transitional seasons.
What is an oversized Sweater?
The oversized Sweater intentionally features more volume around the body, sleeves, or shoulders.
It can be worn with jeans for a casual outfit, paired with wide-leg trousers to embrace an entirely loose silhouette, or combined with a skirt to play with contrasts.
An oversized fit is not simply a classic Sweater chosen several sizes too large: the volume may be part of its construction.
What is a chunky-knit sweater?
A chunky-knit sweater has more volume and can be particularly comfortable when temperatures drop.
However, keep in mind that a sweater's visual thickness alone does not determine how warm it is. Its composition and the construction of the knit also matter.
Also consider the clothes you want to wear over it: a chunky knit naturally takes up more space under a jacket or coat.
What is a crew-neck sweater?
A crew neck follows a rounded line around the neck.
Simple and easy to style, it can be worn on its own or layered over certain shirts, depending on the sweater's cut and the desired look.
What is a V-neck sweater?
A V-neck creates a pointed opening at the front.
The depth of the V varies from one style to another. It can be worn on its own, over a top or with a shirt when the sweater's volume allows.
What is a turtleneck sweater?
A turtleneck rises around the neck and adds an extra layer in this area.
It can be fitted or more relaxed. When it is fine enough, it works particularly well under a blazer or jacket.
The Hello Moon approach
We love easy-to-wear knits that can be worn again and again. Beyond the colour or detail that catches the eye, we also think about the possible pairings with other pieces in your wardrobe.The same sweater can take on a completely different look with jeans, a skirt, trousers or worn over a dress.
How do you choose a women's cardigan?
When choosing a cardigan, focus mainly on its length, volume, knit and fastening.
A cropped cardigan does not create the same proportions as a long cardigan. A buttoned style can be worn closed or open, while a cardigan without a fastening is primarily designed for layering.
Also think about what you want to wear underneath: a T-shirt, top, shirt, blouse or dress.
What are the different types of women's cardigans?
How do you wear a cropped cardigan?
A cropped cardigan can be worn with high-waisted trousers or jeans to play with proportions.
Depending on its cut, it can also be paired with a dress or a skirt.
Buttoned up, it can sometimes be worn as the main piece. Open, it becomes an additional layer.
How do you wear a long cardigan?
A long cardigan extends the silhouette further and lets you play with layers.
It can be paired with jeans, trousers or a dress, depending on its volume and material.
However, check its length if you want to wear it under a coat so that both pieces remain comfortable together.
How do you wear a buttoned vest?
A buttoned vest offers several options: fully closed, partially buttoned, or open.
Worn closed, it can replace a Sweater depending on its construction. Worn open, it lets the top, T-shirt, or shirt underneath show.
How do you wear a women's cardigan?
The cardigan can be used as an extra layer or as a true main piece.
With jeans and a T-shirt, it easily creates an everyday outfit. With a dress or skirt, it lets you add knitwear while keeping more of the outfit underneath visible.

Sweater or vest: which should you choose?
Choose a Sweater if you are looking for a closed piece that is easy to wear on its own.
Choose a vest or cardigan if you want to experiment more with layering and be able to open your knitwear easily.
The two are therefore complementary: a fine-knit Sweater, a chunky knit, and a cardigan do not serve exactly the same purposes.
Fitted Sweater or oversized Sweater: which should you choose?
The choice mainly depends on the volume you want and the other clothes you want to wear with your Sweater.
- A fitted Sweater takes up less space and layers easily under a jacket or blazer.
- An oversized Sweater deliberately adds more volume and can become the main element of the outfit.
There is no need to systematically pair an oversized Sweater with a fitted bottom. Wide-leg trousers or a voluminous skirt can also work if you want to embrace a fuller silhouette.
How do you choose the neckline of your Sweater?
The neckline changes the look of the upper silhouette and also determines how the Sweater can be layered.
- The crew neck is a simple and versatile option.
- The V-neck creates a larger opening at the front.
- A turtleneck or high neckline covers more of the neck and provides an extra layer.
- A more open neckline reveals more of the upper chest.
The best choice depends mainly on your comfort, the style you are looking for, and what you may want to wear over or under it.
What sweater should you wear under a blazer?
To make layering under a blazer easier, a relatively fine knit is generally easier to wear.
A crew-neck, V-neck or lightweight turtleneck sweater can work depending on the blazer’s cut and the desired effect.
The key is to try both garments together: a comfortable sweater worn on its own can become too bulky under a relatively fitted jacket.
How can you tell if a sweater is warm?
To find out whether a sweater provides the desired level of warmth, do not look only at its thickness.
Its composition, construction and knit density also play a role. Two sweaters that look equally thick can therefore provide different sensations.
Before buying, check the composition listed on the product page and also think about how you will wear the knit: on its own, over another layer or under a coat.
The Hello Moon tip
When choosing a knit, think about the complete outfit rather than the sweater alone.Consider what you will wear underneath, but also what you may need to wear over it. A chunky knit can be comfortable on its own but become too bulky under your usual coat.
The goal is to retain enough room to move comfortably when all the layers are worn together.
Which material should you choose for a sweater?
The composition affects the feel, drape, thermal properties and care requirements of a knit.
- Wool is particularly appreciated for its thermal properties, although the feel can vary depending on the type of wool and the garment’s overall composition.
- Cotton can be used in knits of varying weights.
- Mohair is an animal fiber that can, in particular, provide a fluffy appearance.
- Synthetic or artificial fibers can also be combined with other fibers to achieve different effects in terms of feel, durability, softness or care.
Many knits combine several fibers. Therefore, always check the model’s exact composition.
For more information, see our guide to fabrics and care.
Fine knit or chunky knit: which should you choose?
A fine knit takes up less volume and is generally easier to layer under a blazer, jacket or coat.
A chunky knit creates more volume and can become a statement piece in an outfit.
Thickness should not, however, be used as the sole indicator of warmth: the garment’s composition and construction also matter.
How do you choose the right sweater size?
Start by identifying the style's cut: fitted, straight, or oversized.
Then check the ease around the shoulders, bust, and arms. Raise your arms and cross them in front of you to make sure the sweater does not excessively restrict your movements.
With an oversized sweater, more volume is intentional, so do not assess it using the same criteria as a fitted style.
Also consult our Hello Moon size guide.
How can you tell if an oversized sweater is too big?
An oversized sweater is designed to have more volume.
So pay more attention to the length of the sweater and sleeves, as well as its overall volume, rather than focusing only on the position of the shoulders.
The right size is the one that gives you the desired oversized effect while remaining comfortable.
Which sweater should you choose for your body shape?
Body shape helps explain how volumes and lengths visually alter a silhouette. It does not determine which sweaters you can wear.
Which sweater for an A-shaped body type?
An A-shaped body type generally has hips that are wider than the shoulders.
If you want to visually modify this balance, knitwear with more volume or details at the top can create this effect.
A simpler cut will create a different result.
Discover our guide to the A-shaped body type.
Which sweater for a V-shaped body type?
A V-shaped body type generally has shoulders that are wider than the hips.
A relatively fluid sweater or one with less volume at the shoulders helps maintain a softer line if that is the desired effect.
Discover our guide to the V-shaped body type.
Which sweater for an H-shaped body type?
An H-shaped body type generally has shoulders and hips that are relatively aligned, with a less defined waist.
A straight cut follows this line, while a cropped sweater paired with high-waisted bottoms can make the waist more visible.
Discover our guide to the H-shaped body type.
Which sweater for an X- or 8-shaped body type?
X- and 8-shaped body types generally have a defined waist and a balance between the shoulders and hips.
A fitted knit or a sweater partially tucked into high-waisted bottoms can make the waist more visible if that is the desired effect.
An oversized cut will instead create a fuller silhouette.
Discover our guides to the X body shape and 8 body shape.
Which sweater for an O body shape?
A straight, fitted or oversized knit will create different volumes.
The choice mainly depends on the desired result and your comfort.
Discover our guide to the O body shape.
Key takeaway
Body shape is a tool for understanding the effect of volumes and proportions. It is not a list of sweaters that are allowed or forbidden.
How to wear a women's sweater?
A sweater can easily be paired with the main pieces in your wardrobe.
- With jeans, it lets you put together a simple, everyday outfit.
- With trousers, it can create a dressier or more casual silhouette depending on the cuts.
- With a skirt, it lets you play with contrasts between volumes and fabrics.
- With a dress, it can be used as an additional layer and completely transform the way it is worn.
How to wear a sweater with jeans?
The sweater-and-jeans combination is an easy base to adapt.
With a fine-knit or fitted sweater, the jeans' cut remains more visible.
An oversized sweater adds more volume to the top and can be worn with straight-leg, slim, flare or wide-leg jeans, depending on the desired result.
You can also tuck the sweater fully or partially into the waistband when its thickness allows it.
To take things further, see our jeans guide.
How to wear a sweater with a skirt?
A fitted sweater paired with a fluid or voluminous skirt lets you play with the contrast between volumes.
With an oversized sweater, you can instead embrace a looser silhouette or slightly tuck in the front of the sweater when its fabric allows it.
The length of the skirt and the sweater significantly change the result.
How to wear a sweater with wide-leg trousers?
A fitted sweater creates a contrast with the volume of the trousers.
But an oversized sweater can also be worn with wide-leg trousers to create an entirely loose silhouette.
If you want to make the waist more visible, you can partially tuck in the sweater when its thickness and the waistband of the trousers allow it.
How to wear a sweater over a dress?
Wearing a sweater over a dress transforms it and extends its wear when temperatures drop.
Wearing a sweater over it can, in particular, visually give the impression that the dress has become a skirt.
Focus mainly on the volumes: a very loose dress and a very voluminous sweater will create a different result from a more fitted dress paired with an oversized knit.
How should you wear a cardigan with a dress?
A cardigan lets you add a knit layer while keeping more of the dress visible.
A cropped cardigan changes the proportions differently from a long cardigan.
Worn open, it reveals the dress's cut. Buttoned up, it can become a more prominent part of the outfit.
How should you wear an oversized sweater?
An oversized sweater can be paired with practically any type of bottom.
With jeans, it creates a casual outfit. With a skirt, it plays on the contrast between the pieces. With wide-leg trousers, it lets you fully embrace the volumes.
You can also roll up the sleeves slightly or tuck a small part of the sweater into the waistband when its fabric allows, to change the way it falls.
What color sweater or cardigan should you choose?
When choosing the color of a knit, think about the trousers, jeans, skirts, and jackets you already own.
A neutral color can be easy to incorporate into multiple outfits, while a colorful, striped, or patterned sweater can become the main piece of the look.
You can also build your outfit around the color of the sweater or create coordinated touches with accessories.
How should you wear a yellow sweater?
A yellow sweater naturally draws attention and can become the colorful piece of the outfit.
One of the simplest combinations is to wear it with denim and relatively neutral tones.
The shade nevertheless plays an important role: pastel yellow, mustard yellow, and bright yellow do not produce the same result.
How should you wear a pink cardigan?
A pink cardigan can be worn as the colorful touch in a relatively neutral outfit or incorporated into a palette featuring several colors.
With jeans and a simple top, the cardigan easily becomes the main piece.
As with yellow, look at the exact shade: powder pink, pastel pink, or a deeper pink create different combinations.
How should you wear a striped knit?
A striped knit can become the main pattern of the outfit.
For a simple combination, wear it with jeans or solid-colored trousers.
You can also pick one of the colors in the stripes for another garment or accessory to create a coordinated look.
To explore color combinations further, see our color analysis guide.
How should you wear knitwear depending on the season?
What sweater should you wear in spring?
In spring, a fine knit can provide a suitable layer for changing temperatures.
It can be worn alone or under a jacket depending on the weather.
Can you wear a sweater in summer?
Some lightweight knits can be worn on cool evenings or when temperatures are milder.
Pay particular attention to the model's composition and thickness.
What sweater should you wear in autumn?
In autumn, sweaters allow you to experiment more with layering.
A knit can be paired with jeans, trousers or a skirt, then complemented with a jacket when temperatures drop.
What sweater should you wear in winter?
In winter, think about all the layers rather than the sweater alone.
The sweater's composition and construction influence its thermal properties, while the garments worn underneath and the coat also play a role.
Above all, make sure your sweater remains roomy enough when worn with the other layers.
How do you care for a knitted sweater?
Care depends on the sweater's composition. The first rule is therefore to always follow the instructions on its label.
The recommended temperatures, washing programmes and drying methods may vary depending on the fibres and the construction of the garment.
When flat drying is indicated, follow this instruction to limit deformation caused by the weight of the wet knit.
See our fabric and care guide to learn more.
How can you prevent a sweater from losing its shape?
First, follow the washing and drying instructions on the label.
For some knits, folded storage may be preferable to a hanger when the weight of the garment could pull on the shoulders.
Also avoid wringing a wet knit too vigorously.
Why does a sweater pill?
Pilling occurs when fibres protrude from the surface of the fabric and become tangled due to friction.
Their appearance depends in particular on the fibres, the knit construction and the areas of friction on the garment.
Proper care and limiting repeated friction can help preserve the appearance of the knit.
Frequently asked questions about women's sweaters and cardigans
What is the difference between a sweater and a cardigan?
A sweater is generally closed at the front and pulled on over the head. A cardigan is a knitted garment that is open at the front, often with buttons.
What sweater should you wear under a blazer?
A relatively fine knit is generally easier to layer. Above all, make sure the two garments allow you to move comfortably around the shoulders and arms.
What sweater should you wear with high-waisted trousers?
A cropped, fitted, or partially tucked-in sweater makes more of the trousers' waist visible.
An oversized sweater can also work if you want more volume.
How can you make an oversized sweater look dressier?
Pair it with trousers or a skirt whose cut matches the look you want, then use shoes, a bag, and jewelry to adjust the level of sophistication.
How can you wear a shirt under a sweater?
Choose a sweater with enough room to accommodate the shirt without restricting your movements.
You can let the collar, cuffs, or bottom of the shirt show, depending on the lengths of the two pieces.
Do you need to choose a larger size to get an oversized sweater?
Not necessarily. A true oversized sweater can be designed with more volume from the outset.
Check the style's fit and measurements before choosing a larger size solely to achieve this effect.
How can you tell if a sweater is itchy?
The sensation depends on the fibers used but also on your personal sensitivity.
Check the composition of the style and, when possible, try the knit against your skin. A lightweight top worn underneath can also change how it feels.
How can you tell if a sweater is warm?
Don't rely solely on its thickness.
Also look at its composition and knit construction, then consider the other layers you will wear it with.
How can you wear a cardigan without looking too classic?
You can create contrast by pairing the cardigan with more casual pieces such as jeans, a T-shirt, or sneakers.
The way you button it, its length, color, and accessories can also completely change its style.
