You can count on these 15 bestselling looks on M&S to help you beat the heat in comfort and style
From tees to breezy dresses and luxe linen trousers, these are the items missing from your summer wardrobe
I know none of us wants to be wearing clothes right now, but if you are having to get dressed, or leave your house, you may as well nail what to wear in the heat and look and feel good whilst doing so. M&S have had a fantastic season, and it feels like the British clothing brand is going from strength to strength, and these 15 bestsellers are sure bets to help you beat the warm weather.
As with all of our hot-weather style content, whether it's the best summer dresses, great tees or staples to add to your summer capsule wardrobe, you largely want to look for natural fabrics such as linen or cotton, as well as airy, relaxed shapes. This will help get the maximum air to your skin, keep clothes breathable and make you feel less hot.
Whether you're a self-confessed dressoholic, love the comfort of trousers, or just need a t-shirt update, M&S has the answer. Alongside its own brand line, it now also stocks lots of other high street brands, so you can really get a great selection and plenty of choice in terms of style, size and fit.
Available in three colours, this applique t-shirt is the quickest way to style-up any outfit. From jeans and tees when the temperature drops a little, to a quick and pretty solution to reworking a summery A-line skirt. The short sleeve adds upper arm coverage.
This cardigan is one of the brand's top sellers. Available in cream, brown, orange and zesty lime, it's the perfect little cover-up at home or abroad. Where buttoned as a top with the matching shorts, or slip it on over vest, camis or sleeveless dresses for light coverage.
Linen trousers are a great option for warm weather thanks to their breathability and this balloon shape adds a contemporary feel to a summer classic style. The cuffed hem creates a rounded shape, more exaggerated but just as flattering as your best barrel jeans.
With a crinkle effect and a golden hue, these elegant balloon trousers offer an excellent transition from day to evening. The voluminous, rounded shape echoes the latest denim trends for 2026, while the fabric has a much more high summer feel.
In a cotton blend, this airy short-sleeved blouse is the ideal hot weather piece for the office. Team with linen or cotton trousers in a similarly neutral hue for a simple, yet sophisticated outfit. The Broderie trim keep this sweet blouse on trend.
Skater skirts offer maximum breathability, even with synthetic fabrics, as the big airy silhouette ensures you can truly catch the breeze. The asymmetric seam detailing helps to draw the eye down the body, lengthening your shape.
Holiday weather deserves some holiday trousers, and this gorgeous blue and white combo will have you ready for sandy beaches, aperol spritzes and most importantly, rising temperatures. Linen rich, you get breathability with less creasing, and a comfort waist.
If you are busy stocking up on those summer evening looks, this is the date night outfit idea that's sure to turn heads. The floral applique adds depth to this simple mini shift, that could also work over skinny jeans in slightly cooler climes.
I love a tiered maxi skirt in the summer, as it offers gorgeous, breathable coverage, which is key for me in hot weather. Airy enough to help keep you cool, the floral print keeps it summery and easy to style, as you just need to pick out an accent colour from the bloom design.
Shorter, fuller sleeves in a relaxed cut helps to add an airy feel to this viscose/polyamide blend blouse. With a gently bohemian feel thanks to the ruched body. The gathering creates a flattering fit throughout, skimming your shape. Pair with linen trousers or jeans.
Pure cotton clothing is one of the best investments you can make for your wardrobe and this super pretty, embroidered dress features thick straps for great shoulder coverage - so you can wear your favourite bra. The empire seam detail skims your middle and lengthens your shape.
THE LBD never goes out of style and this is one of the brand's best sellers from the just in edit. Sleeveless, but with wide straps, a midi length and fringe detailing, it's easy to style up or down. Add a denim jacket and trainers for a casual spin, or a statement necklace and heels for an event.
Pure cotton, a chic paisley print and short, airy sleeves that offer perfect upper arm coverage, the drop waist is a contemporary silhouette for the summer that will be flattering for seasons to come. At under £50, this is a summer dress you'll wear on repeat.
A selection of classic cotton t-shirts is a capsule wardrobe must and M&S unsurprisingly make some of the best. Available in a wide range of colours, I always recommend stocking up on neutrals and some trending hues to underpin your wardrobe.
If you have torn yourself away from the cooling climes of your fridge, and have to head to an event, then this beautiful maxi dress is the hot weather choice you should be making. Bold blooms, gorgeous greenery and sweet fluttery shoulders make this a hot weather hero.
M&S heatwave best sellers
With several days left of the heatwave, followed by several more days of summery climes, sorting your summer wardrobe is very important. Natural fibres are the breeziest, offering breathability, even when you're more covered.
When you're topping up your summer wardrobe, think about existing hot weather heroes and how you can best extend their lifecycle, restyling them for new occasions or warm weather moments. Refreshing your t-shirts can up-style skirts or trousers, while a new dress can give you a whole new look and feel.
M&S is well known for its quality, and alongside other standout British brands, it's helping to dress the nation in style and comfort. Aside from breathable fabrics, look for comfort elasticated waistbands, as these will be easier in swelting temperatures, and airy silhouettes such as trapeze, A-line, or wide leg styles help with breathability too.
