This is the best sports bra! I'm a 34 b/c so I got the medium size. I take Krav Maga classes, which is a high impact workout and I was surprised at how it held everything in place and still maintain my girly shape. My old sports bras either felt like I was wrapped in duct tape that my boobs have disappeared, or it was too loose that things were bouncing all over. I love the zipper feature, too: it's so easy to put on/take off!! I highly recommend this for all the busty ladies who still want to look shapely during their workouts ;-)
