NWOT Model 5021C This Sports Bra is designed to reduce breast bounce by up to 83%. A unique bra designed to hold each breast to reduce movement in all directions. Underwire cups Lightly moulded design Adjustable straps New, never used. I wear a 36I cup in Freya and this was a bit too roomy above the breast area. Probably would work for someone with breasts that have more volume on top.
