Square-Neck Midi Dresses at M&S

Our women’s square-neck midi dresses are modern ways to approach a classic style. We have your favourite shapes, from shifts to tea dresses, all cut to a neat below-the-knee length. As wide, square necklines draw attention to your collarbone and balance your silhouette, you’ll find these midi dresses are reliably flattering. Our collection is packed with inspiring designs from well-known brands such as Nobody’s Child, Finery London and Albaray.

If your wardrobe already contains V-neck midi dresses and midi dresses with round necks, add a square-neck style to mix things up. Quality fabrics with touchable textures mean linen dresses are must-haves for smart-casual outfitting. Choose navy dresses to get work ready, or go for midi column dresses if your tailoring needs an update. When worn under slim-fitting blazers and paired with sleek high-heel shoes, square-neck dresses are effortlessly chic options.

It’s easy to pick out comfortable and stylish pieces for your holidays with our ladies’ square-neck midi dresses. Discover mid-length options with floaty tiered skirts that move with you as you walk. Details including slim straps and smocked bodices emphasise low and angular necklines. A-line designs from our selection of black dresses are versatile enough for day and night. Pulls yours over a bikini or swimsuit when you’re at the beach, then add a clutch bag and striking jewellery for women to transform it for the evening.
