How we pick

Nobody here is paid to push a brand. Ellie, Lauren, Rosie, Chloe and Megan went through everything in sleeveless party backless dress the way you would on a lunch break, scrolling, squinting at the fabric, checking the price twice. What made the list is what they'd actually put in their own basket. We look for pieces that wash well, sit right and don't cost silly money for what they are, and we mix up the shops so you're not just looking at one high street name over and over. Prices and stock come straight from the retailers and change often, so it's always worth a quick check before you buy.

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
