DD, (11) I think is ready for first bra as has developed early.
She currently wears these m&S basic, thin crop tops, but I think she is maybe a AAA and needs more support or a small cup I'm not sure?
I was going to measure her and look at options but she doesn't want me to measure her and says she wants to stay with crop tops and avoids the subject. I said no problem if you are not ready.
Is it a problem if I just leave it a year or so and keep her in crop tops that don't have much support? Or should I tell her it's important to have a bit more support and encourage a trainer bra?
