7 Summer Outfits to See You Through This Week's Heatwave

As anyone living in the unpredictable English climate knows, dressing for spells of warm weather can be challenging. If you've ever asked the age-old questions Will I need to bring a jacket? and Is that… rain? you'll know that consistency isn't Britain's forte, but judging by the current forecast in the UK, the next week is looking optimistically sunny, and I am ready for it. 

As someone who has now had plenty of experience in strategic layering, I thought I would take some time to share my knowledge of how exactly to dress when the mercury rises (and it does involve some sensible sleeves, just in case).

From clever co-ords to reliable dresses, there's no one formula when it comes to dressing for warm weather. And at the end of the day, it's all about what makes you feel cool and comfortable, as both factors are a top priority when outfit planning.

Think breathable fabrics, fluid silhouettes and plenty of print and colour, as seen on the fashion set. In fact, between the linen separates, versatile accessorising and sun-smart tailoring, it seems several of our favourites have perfected warm-weather dressing. Keep scrolling for seven summer outfit ideas for what to wear in a heatwave. 

1. The Linen Co-Ord + Sandals

Style Notes: For the hottest days when you want the easiest outfit, look no further than the linen co-ord. An airy, light shirt and comfy shorts make a surprisingly chic option that is guaranteed to keep you cool. Just add slides or sandals for your new weekend uniform. 

Shop the Look:

H&M's linen shirts are the kind of premium quality that don't go sheer or crease easily. Pair one with the brand's matching shorts to double up on this easy, breezy style (no ironing required). 

At this price for a full look, we aren't complaining. 

A slouchy tote big enough to hold everything you'll need for work, shopping and anything in between. 

Chunky sandals are still a firm favourite this summer.

2. The Waistcoat + Linen Pants

Style Notes: Okay, hear me out. Yes, it's more linen, and yes, the thought of tailoring in summer might sound hot, but far from a stuffy three-piece suit, a simple waistcoat with shorts or wide-leg trousers adds polish to an otherwise casual look, and keeps you cooler for longer.

Shop the Look:

If black feels too heavy, swap in neutrals like camel, cream or white that will work just as well with jeans and loafers when the weather gets cooler. 

Balance the structured tailoring of a waistcoat with soft linens. 

Add retro cool with this pair of sunnies, my favourite from Le Specs. 

3. The Silk Resort Shirt + Shorts

Style Notes: Nothing says summer like dopamine dressing. Cue the bold and beautiful printed silk shirt. The short-sleeve bowling style is taking over my feed right now, and the loose silky feel is a welcome change from a clingy jersey tee.

Shop the Look:

Less "dad" shirt and more tropical graphics and florals, these ultra-comfortable shirts are the stylish evolution of your favourite pyjamas. 

A classic pair of khaki shorts is a summer staple, and investing in a pair like these from Ralph Lauren will keep you covered for years to come.

We're calling it: platform flip flops are set to be the sandal of the summer. 

4. The Nap Dress + Block Heels

Style Notes: The dreamy nap dress, so known for its proximity to a vintage nightgown, is one of my current obsessions. There is almost no styling required with this bed-to-brunch option, saving you valuable time getting ready in the morning. 

Shop the Look:

If the reviews are anything to go by, the fit and fabric make Sleeper dresses a surefire winner.

Big-heel energy in a far more comfortable low, block style. 

The perfect finishing touch to any outfit.

A buttery leather top-handle makes the perfect shoulder bag. 

5. The White Tank + White Shirt

Style Notes: For an exercise in understated layering, simply add a white shirt over a tank top to channel the cool-girl brand of less is more.

Shop the Look:

Made from organic cotton and treated with peppermint oil to help you stay cool and fresh. 

The Who What Wear editor's tank of choice. 

A midi skirt goes with everything, and I'm swapping out the dark jewel-toned satin skirts I wore through autumn for this summery, pastel iteration. 

BRB, adding this handbag to my wish list ASAP.

6. The One Shoulder Dress + Statement Heels

Style Notes: For the perfect summer wedding guest outfit, add party flats to an asymmetric dress, and take your daytime look up another level.

Shop the Look:

From David Koma to Gucci, the red hot colour palette is a mainstay for spring summer 2023.

Add the finishing touch to this dressy look with a pair of this seasons hottest earrings.

Who What Wear's Emily Dawes is already sold on this trouser trend, but the latest way to wear it? With the scarf top of former Y2K glory. This look might not be for the fainthearted, but fear not: The scarf can be stylishly repurposed as a headscarf as seen on Emili Sindlev.
