I'm looking for a 30d non padded bra for my 11yr old to wear under school uniform. So white or nude. Have looked in the usual places. Helpful shop assistants so far have suggested I'm looking for the wrong size(!). Her 30c bras are no longer fitting - the central gore in not flat against her chest. Have tried a 32c which fits better in the cup but too big in the back.
Any suggestions?
