I have the worse time finding a bra that fits. Ususally, I buy 46-48 B. Not one bra to date has given me the lift I was looking for until now. I ordered the C, thinking well it is probably too big. Because of the lift this bra gives you, the C cup was perfect!!! I can't wait to order another. Finally, a bra that lifts, no underwire, and comfortable! Just remember, it does lift, so you may need to adjust your cup size.
