How to wash jeans?

One of the best features of a denim jacket or jean jacket is its ability to transition seamlessly from season to season. During spring and summer, a light denim jacket provides just the right amount of coverage for those cooler evenings. As temperatures drop, you can layer one over chunky knit sweaters, add scarves, and even wear under outerwear for added warmth in the autumn and winter.  Styling tip: When it’s cold out, wear your jeans jacket under a trench coat or a wool top coat to create a stylish, multi-layered look.

• For work: A denim jacket worn with wide leg tailored trousers and a tucked-in oversized stripe shirt will always look great.
• For casual occasions: Double denim is the way to go! Or if you prefer, a denim jacket worn with leggings and a hoodie gives a sporty yet modern aesthetic.
• For going out: Choose a black maxi dress and amp up the accessories, or a pair of faux leather jeans and a silk top for an elevated evening ensemble.

What to wear with a denim jacket

When it comes to choosing what to wear with a denim jacket, there are many combinations that we’d recommend. In 2025, the denim jacket continues to be a wardrobe essential, yet the way we style it is constantly evolving. Keep your overall look fresh and of-the-moment by layering. Think oversized denim jackets worn over loose shirts or colourful knitwear. Layering creates depth, balances texture and makes a style statement. Alternatively, the contrast between tough and soft styles is a standout trend, so team your denim jacket with a floral dress, or a flattering satin blouse with your favourite smart trousers and heels.

The denim jacket's ability to blend with a wide range of styles makes it a versatile piece for every woman's wardrobe. Style yours in a way that best reflects your personality.

How should a denim jacket fit?

The fit of a denim jacket is key to creating a flattering and stylish look. Here's the most popular denim jacket fits:

How to wear double denim

Double denim, also known as the "Canadian tuxedo," is a bold, stylish look that involves wearing denim on both the top and bottom.

The key to mastering the double denim rule is by complementing washes and textures. Avoid wearing contrasting wash pieces. Instead, pair a light-wash jacket with light blue jeans and break up matching shades with oversized shirts or bold accessories.

You might also want to consider their proportions and cuts; a wide-legged pair of denim jeans will balance well with a denim jacket with a slightly narrow fit. Alternatively, opt for a retro look and style a pair of high-waisted slim-fit jeans with an oversized denim jacket and layer with a button-up denim shirt in the same shade.

Pair with neutral footwear such as white trainers or ankle boots to keep the outfit fresh and modern, however always remember - less is more when it comes to creating an effortless double denim look.

How to style a long denim skirt
