The gilet (or body warmer) is the most practical layer in a British wardrobe. It keeps your core warm while leaving your arms free, fits under or over almost anything, and bridges the gap between a jumper and a coat. The short answer: wear it close-fitting, in a dark neutral, over a jumper or shirt in mild weather, or under a coat when it turns cold. Here is how to wear a men's gilet so it looks smart rather than sporty.
Why wear a gilet?
- Extra warmth without the bulk of a full jacket.
- Perfect for changeable spring and autumn weather.
- Easy to layer over knitwear or under an overcoat.
A gilet is simply a sleeveless jacket, usually quilted or padded, that fastens at the front. Because it has no sleeves, it adds warmth where you need it without restricting your arms, which makes it useful for driving, cycling, walking the dog or sitting at a desk. If you are new to the garment, our explainer on what a gilet is covers the main types.
The rules of wearing a gilet
- Treat it as a layer, not a coat. A gilet works with what is underneath it. Plan the jumper or shirt first.
- Keep it slim. A close fit looks smart. A loose, boxy gilet looks like outdoor kit.
- Choose sleeves with some texture. Knitwear, Oxford cloth, brushed cotton and corduroy all look good beside a quilted body.
- Contrast the colours a little. A navy gilet over a grey or cream jumper shows off both pieces.
- Match the gilet to the occasion. Plain, matt and dark for town and the office; more rugged styles for the countryside.
How should a gilet fit?
A men's gilet should sit comfortably over your intended base layer, close through the body without pulling across the chest. The hem should finish around the hips. Armholes should allow movement without excessive gaping.
- Chest: fasten the gilet over the shirt or jumper you plan to wear. The front should sit flat without straining.
- Movement: reach forward and lift your arms; the shoulders and armholes should not restrict you.
- Length: check that the hem covers your waistband without bunching when you sit.
- Size: compare the product measurements with a similar garment that fits. Leave room for knitwear and consult our size guide before sizing up.

7 gilet outfits for men
1. Gilet over a quarter zip
The smart-casual classic. A navy or black gilet over a knitted quarter zip, with chinos and loafers or trainers. Keep the knit a shade lighter or darker than the gilet, and choose men's chinos in stone or navy. For more ways to wear the knit itself, see our quarter zip jumper outfits.
2. Gilet over a smart shirt
For milder days, wear a gilet over a long-sleeve smart shirt with straight leg jeans. Leave the gilet open or half fastened so the shirt collar and placket show.
3. Gilet with a hoodie
A relaxed weekend look: gilet over a pullover hoodie with joggers and trainers. Pull the hood out over the collar of the gilet and keep the colours simple, such as grey with navy or black.
4. Gilet under an overcoat
On the coldest days, a slim gilet under an overcoat adds warmth without anyone noticing. This only works with a thin, lightly padded gilet. If the coat feels tight across the back, the gilet is too bulky for the job.
5. Gilet over a cable knit
A country-inspired outfit: gilet over a cable-knit jumper with cords or chinos and Chelsea boots. The texture of the knit against the smooth quilting is what makes this look work, and men's corduroy adds a third texture below.
6. Gilet over a roll neck
For a sharper evening or office outfit, wear a dark gilet over one of our roll neck jumpers with tailored trousers. The high neck fills the space where a collar would sit and keeps the outline clean.
7. Gilet over a check shirt
A plain gilet calms down a pattern. Wear it over one of our men's check shirts or brushed cotton shirts, with dark jeans and boots, for a Saturday in town or a walk to the pub.
What colour gilet should you buy?
Navy and black are the most versatile and easy to dress up. Olive and khaki suit weekend and outdoor outfits. Keep the layers underneath in contrasting tones so the gilet stands out.
If you are buying one gilet, navy is the safest choice: it works with grey, cream, camel, burgundy and denim, and it looks at home over a shirt in the office. Black is slightly more urban and suits monochrome outfits. Olive and khaki pair well with cream knitwear, check shirts and brown boots. Whatever the colour, a matt finish tends to look smarter than a high shine.
Wearing a gilet through the British seasons
The gilet earns its place because British weather rarely settles. It is easy to carry, quick to fasten and simple to add to an outfit you are already wearing.
- Spring and autumn: wear the gilet as your outer layer over a jumper or shirt. It handles a cool morning and comes off easily by lunchtime.
- Winter: use it as a mid layer between knitwear and a coat. Our guide to layering menswear for a British winter explains how to build this without bulk.
- Summer evenings: a light gilet over a long-sleeve shirt or polo is enough for a barbecue or a coastal walk once the sun drops.
- Rain: a gilet leaves your arms uncovered, so in steady rain wear a coat or one of our men's lightweight jackets over the top.

Where to wear a gilet
- Office: a plain navy or black gilet over a shirt or quarter zip, with chinos or tailored trousers. Keep it slim and take it off for formal meetings.
- Weekend in town: over a jumper or hoodie with jeans and trainers.
- Countryside: over a cable knit or check shirt with cords and boots.
- Travel and commuting: a gilet is easy to wear on a warm train and adds useful pockets without the weight of a coat.
- Pub or casual dinner: over a roll neck or fine knit from our men's knitwear, with dark trousers.
Gilet mistakes to avoid
- Wearing a gilet that is too long or loose, which looks shapeless.
- Pairing a technical gilet with formal trousers. Match the gilet to the outfit.
- Wearing it over a heavy puffer jacket. One padded layer is enough, so choose between the gilet and one of our men's puffer jackets.
- Wearing it over a short-sleeve T-shirt with nothing else. Bare arms and a padded body look unbalanced; a long-sleeve layer works better.
- Overfilling the pockets, which pulls the front out of shape.
- Choosing a gilet so tight that it will not fasten over a jumper.
Frequently asked questions
How do you wear a gilet without looking too sporty?
Choose a slim, plain gilet in navy or black with a matt finish, and wear it over smart layers: a quarter zip, roll neck or Oxford shirt. Add chinos or tailored trousers and leather shoes or clean trainers. Avoid bright colours, shiny fabrics and technical details if you want the gilet to look smart rather than sporty.
How should a gilet fit?
A gilet should fit close through the body without pulling across the chest when fastened over a jumper. The hem should finish around the hips and cover your waistband, and the armholes should let you move freely without gaping. Try it over the thickest layer you plan to wear underneath before deciding on a size.
Should you size up in a gilet?
Not automatically. Start with your usual size and compare the product measurements with a similar garment that already fits you. If you plan to wear the gilet mainly over thick knitwear, check there is room across the chest when it is fastened. Only size up if your usual size strains over your intended layers.
What do you wear under a gilet?
Long-sleeve layers work best: a quarter zip, crew neck, cable knit or roll neck in cooler weather, and an Oxford shirt or long-sleeve polo on milder days. A hoodie works for relaxed weekends. Choose a colour that contrasts slightly with the gilet so both layers are visible, such as grey or cream under navy.
Can you wear a gilet to the office?
In most smart casual offices, yes. Pick a plain, slim gilet in a dark colour and wear it over a shirt or fine knit with chinos or tailored trousers. It is a practical layer for a cold commute and a cool office. For formal meetings or client-facing days, a jacket or overcoat is the safer choice.
Can you wear a gilet under a coat?
Yes, and it is one of the most useful ways to wear one in winter. A thin, lightly padded gilet under an overcoat adds warmth to your core without making the sleeves tight. Make sure the coat still fastens comfortably and the gilet hem does not hang below the coat.
