Crafting chic and affordable dresses comes naturally to high street hero M&S. From the sell-out zebra print midi dress—reminiscent of Réalisation Par’s Gia style to the Ganni-inspired leopard print frock with playful bows and elegant puffed sleeves, the brand is responsible for numerous viral favourites, adored by fashion insiders and editors alike. This season, however, one standout M&S dress is set to become a best-seller for spring and summer – not because it resembles a designer favourite, but because it’s effortlessly stylish, comfortable, and priced at under £30.

Introducing the M&S Round Neck Shirred Dress, the mini that’s set to become a key staple in your spring and summer wardrobe (and even autumn and winter with the right styling). With its chic, fitted bodice and airy mini-length skirt, this shirred design strikes the perfect balance of practicality and style. Made from soft cotton, it keeps you cool and comfortable while offering a flattering silhouette that pairs effortlessly with jackets and lighter layers, like cropped trenches—unsurprisingly, M&S offers the perfect shortened trench coat that’s as timeless as it is contemporary.

But the true brilliance of this M&S dress lies in its commitment to size inclusivity – not only is it available in sizes 6-24, but it also comes in petite, regular, and tall lengths. While the petite and regular versions still have plenty of sizes in stock, the tall iteration is already selling out fast, with only two sizes remaining. If history is anything to go by (M&S has a proven track record of creating viral wardrobe staples), this dress won’t be around for long.
