What bra size is my daughter?

[Titsywoo]

Under bust is 29 and over is 35 inches. She's currently wearing a 30DD but says it feels really tight on the band. I need to order her a bra online as we go away on Thursday and have no time to go shopping before that. Thanks :)

Try a 30E or F? A 30 band should fit with room to spare but if the cup is slightly too small, it will likely feel tight. She could probably wear a 28FFish in many brands. In fact I reckon something like a Freya Deco In a 28FF would probably be a pretty good fit.

Fairy Boobmother on Facebook has a fab group and will be able to help you. she's a professional bra fitter, so knows which brands sizing runs which way (if that makes sense!).
