Whether you're heading off on holiday and need to combat a coastal breeze, or enjoying an evening with friends in your local pub garden, a lightweight layer is always worth having.

The bomber jacket

If there's one silhouette that continues to dominate, it's the bomber jacket. Relaxed, lightweight and endlessly versatile, it's ideal for warmer weather thanks to its roomy shape, which allows plenty of airflow without clinging to the body. Throw one over everything from summer dresses to denim Bermuda shorts for an effortlessly cool finish.

Something sheer

From transparent dresses to sheer tops and barely-there jackets, see-through fabrics featured prominently across the SS26 runways. Ralph Lauren showed a crisp white organza belted funnel-neck jacket, while Fendi embraced texture with an open-weave embroidered bomber. Despite appearing as outerwear, these styles blur the line to function more as a statement top, making them the perfect finishing touch for summer occasions.

A classic denim jacket

Some trends never date, and a denim jacket is one of them. This season, to keep your look feeling fresh, stick to relaxed fits, whether that's a cropped boxy cut or an oversized chore jacket. Wear them with all your summer staples, from dresses to linen trousers, they're sure to be one of the hardest-working pieces in your wardrobe.

The technical jacket

Utility dressing continues to have a major moment. From lightweight windbreakers to sleek technical jackets with sporty connotations, this trend is as functional as it is fashionable. Not your usual vibe? It’s totally fine to pair yours with a floaty white midi skirt over bike shorts. Opt for a statement shade like chilli red for extra style points.

Not your basic blazer

A blazer is a perennial wardrobe staple, but summer calls for a lighter approach. Swap your trusty black go-to version for a linen style in a soft, pale tone. Cream is a classic, but a subtle navy stripe adds extra interest, or for the more adventurous, pistachio green is proving popular right now.
