DD (14) is a dancer. She needs a bra for her next show which has transparent straps and a transparent back so that it doesn't show under her costume. Does such a thing exist?!
Last year, I bought a "dance bra" off the internet but it was horrendously uncomfortable and she couldn't wear it.
She's around a 30B or maybe 32B, need to get her measured again. The bra colour should be "nude" but the straps/back need to be as close to invisible as possible!
