Hi, DD wants a bra, been wearing crop tops up to now and I agree now is probably the right time. She measures 25 inches under bust (around rib cage) and 28 inches around bust, I think this is a 25B/C cup but I could be totally wrong and also where am I going to find a bra that is a 25 underbust as I’ve never seen one for sale! Any help gratefully received!
