I count myself luck inasmuch as I had the advice to go right down in the back size and up in the cup quite a long time ago and am happily well supported! I would like to ask about my daughter though. She's 13, and very small, but growing. She's still in the league of crop tops imho, but wants to have bras to wear, particularly when they change for PE in school...to be like the others, many of whom have been in bras for quite some time.
I bought her first bras at M&S (as we all did, although I have never got my bras there as an adult), and she started off with a 30A, although at the time I felt that her back size really should have been smaller (and it has started to ride up), but the 28's are perpetually sold out.
Well, I had another measure of her, and she's 27" and a half, under bust but 31" and a half over. Despite looking very small would this make her, maybe 28 B/C? and if so, where to buy? I don't like the underwired and moulded teen bras at M&S, and I really can't see the point of the ones that are padded, but would welcome advice on this too. Many thanks in advance.
