Boux Avenue Odette Deco Longline Bra (£36)
"Apparently, this bra is so popular, one is sold every 20 minutes! It's easy to see why, as it combines comfort and practicality with some serious style. As a bonus, it's also available in a big range of sizes, from 30A to 38G, and a whole host of colours. Black and beige are safest if you're gifting it!" — Gemma Cartwright, senior editor, UK
