How we pick

Quick word on how this list was made. Dani, Aisha, Rosie, Esme and Chloe picked their favourites from the black onesie we found across loads of UK shops. No sponsored spots, no brand deals, just what they'd buy with their own money. We keep a mix of prices so there's something whether you're treating yourself or being sensible this month, and we limit how many come from one retailer. Stock and prices update regularly from each shop, so if something's gone, it's sold out rather than hidden.

We may earn a small commission if you buy through links on this page. It costs you nothing extra and helps keep the site running. How we make money
