Ah, if you're a 28JJ then definitely look into the Curvy Kate suits (amazon UK has a sale right now for 25% off with the code EASTER25). Lovebras have them listed there too. Check the blogs BrasIHate, ThinandCurvy, and Boosaurus, By Baby's Rules, well, and mine too.

We're all 28 backs or under.
Good luck, I hope you find something wonderful!
