I have 41C mature breasts so I really need shape and support. I love how an underwire shapes me (especially balconettes) but they are constricting and I just want them off by the end of the day.

This bra is different It's so well balanced that there are no strain points.  The girls are well shaped and separated and most important, held up. Typically with a wireless, there's always some shape issue or some flesh poking out on the side, or something sagging or not enough definition between. But this one is perfect. And I'm as comfortable at the end of the day as at the beginning. I'm buying another. I purchased from Bare Necessities.
