Once your daughter’s size is established, be prepared to buy at least two bras: one that’s sensible, comfy, and well-made, another that’s sweet, lacy, and (dare I say…) a wee bit sexy. Grin and bear it. Let your daughter chose both. If tensions flare, call back the bra-expert for impartial opinions (and to break up any headlocks). And don’t forget the matching undies.
