Everyone on My Instagram Feed Is Wearing Dresses From COS, and I Can See Why
Fashion people have been buying COS dresses in bulk this season, and I'm following suit. Here are the 19 best COS dresses to treat yourself to now.


When your job is to find emerging trends and showing your fellow fashion enthusiasts each brand's seasonal must-haves, you need to be an open-minded shopper. Very rarely will I disregard a trend before trying it for myself. But admittedly, I tend to shop in certain stores for certain items. Take & Other Stories, for example. As soon as I cross its threshold (both in real life or online), I know I'll come away with one of two things: a pair of jeans or a great dress. Similarly, Mango is my one-stop shop for shoes, while Zara serves as my go-to for blazers. Linen? Reformation. Wardrobe staples? Arket. And so on.

The downside is that I'll sometimes enter a store with blinders on, seeking out the pieces I usually buy instead of taking in what else is on offer. But I've recently learned the error of my ways. I'm a dress girl through and through, and lately, all of the frocks I've been admiring are from one place: COS.

Previously, I'd have never considered COS a dress destination. (My COS purchases usually start and end with t-shirts and wide-leg trousers.) But after discovering these styles, I know I'm going to be hooked on its frocks from here on out. I keep spotting my favourite influencers donning COS styles, and naturally, I now plan on joining them. Keep scrolling to shop my edit of the best COS dresses.
