What To Wear To Work When It’s 30 Degrees Or Above

With the threat of another heat wave hitting the UK this July, it begs the question, what on earth will we wear to work? Whilst sunny days at the weekend create a collective lifting of spirits, it’s less than fun when you have to work, commute and dress appropriately in temperatures 30 and above.

The key to staying cool and looking smart is choosing the right fabric. Stay well clear from manmade materials, instead opting for linens, silks and organic cotton. You don’t want to go too tight either, loose, wafty layers will keep the air circulating and your temperature down. Plus, if you’ve ever fallen victim to the fridge freezer level of office air-con, you’ll know having an extra layer on hand is a must. And finally, just because it’s hot doesn’t mean you have to wear as little as possible. Keeping some areas covered can help to keep you cool, so a loose linen shirt may in fact work better to stop the schvitzing than say, a strappy top.

We’ve trawled Instagram to find some of the best warm-weather looks fit for the office. From tailored linens via Anine Bing to breezy silk trousers on Amy Appleton Dreyer, scroll to recreate the looks and shop some summer-approved basics.


Amy Appleton Dreyer, AKA Steps of Style, perfectly showcases how to do layering for summer. Go for a silky trouser fabric rather than classic cotton or wool to keep things feeling nice and cool against your skin, and an oversized blazer will feel fresher than more tailored options.

We love this riff on a classic business look demonstrated by content creator Marilyn Nwawulor-Kazemaks. Her classic striped button-down by With Nothing Underneath comes with oversized cuffs for a nonchalant, ‘borrowed from the boys’ look. Keep things pulled together but not too constricted with a pair of tailored Bermuda shorts and strappy mid-height heels.

The waistcoat has become the unlikely hero of summer 2023, whether worn with denim shorts or over pretty prairie dresses. They naturally work well for the office too, given their roots in suiting, but worn along and a little oversized not only feels modern and cool but is actually a cooler option for warm weather days too.

Look to The Frankie Shop for great linen options in biscuity hues that come with matching trousers, shorts and blazers, should you want to rock the full set.

‌Keep accessories to a minimum with tan sandals and statement chunky gold earrings.



This look by Mariam Kukhalashvili feels so polished but is comfortable for warm temperatures. If the mercury does start to rise more towards 40 degrees, consider swapping the body for a wafty linen or silk shirt, as seen here on Annemiek Kessels, AKA @modedamour.

‌Add a canvas tote roomy enough to fit in everything from gym kit to laptop – we love this affordable option from John Lewis – and use it as a beach bag come holiday time.

Few do laid-back LA tailoring quite like Anine Bing. The designer wears her off-white linen suit with a simple white tee and elegant sling-backs – but it would work well with this season’s chunky flip-flop sandal too. Keep accessories, hair and makeup lowkey and let the suit do the talking.
