How we pick
Every collection on What She Wears starts with a pile of products and ends with a short list chosen by real women. For backless sleeveless party dress, that was Tamsin, Aisha, Ellie, Freya and Megan. They looked at shape, fabric, reviews where there were any and, honestly, whether it made them want to wear it this weekend. Things that look great on a model and terrible on a hanger tend to get cut. The full list underneath is everything that matched, from lots of different shops, so you can still have a proper browse.
