This M&S mini denim dress is the perfect spring uniform

Light-wash denim has forever been a spring staple. But the denim dress? How the fashion set is wearing blue-wash cotton this season. Of course, the trend has roots on the designer runways — specifically Emilia Wickstead, Zimmerman and Marques’ Almeida.

Dark-wash mini dresses and corset-style midi dresses featured in both the brand’s 2026 spring and fall collections, suggesting that this trend will see us all the way through to the end of the year.

But if there’s one place to head for those keen to invest, it’s Marks & Spencer, whose latest viral hit suggests we should be focusing on the cut and texture of our denim this season.

Yep, this shift-style denim spring dress is doing the rounds on Instagram and TikTok, mainly because it looks far more expensive than it is — and that square neck? Universally flattering. It’s no surprise, then, that it’s already a bestseller, despite only landing on site last week.

Other perks, aside from its sub-£50 price tag? The fact that it’s available in every size from a UK 6 to 24, and in three lengths: petite, regular and tall. Plus, being 100% cotton, it’ll keep you cool on your morning commute. But I also can’t help but think that the tufted fabric, almost with a tweed-like effect, makes this look like it could be a member of Chanel’s latest Ready-To-Wear collection.
