Our T9 bra guru is a DD who is serious about her bras. Her skeptical eye and rigorous testing have put many a bra at the top, or the bottom, of our heap. She developed this bra for her very own self and it's now in our catalog "cuz she says so." It's made of a breathable Coolmax mesh but it ain't no lightweight bra. Underwire, powermesh and stabilization panels mean this bra holds up under the rigors of a workout and measures up to everyday comfort requirements. Best for C, D and DD cups who want their bra to go from work to workout. Only at T9. By Moving Comfort. 32-38 B, 32-40 C-DD
