holds everything in place even with out an extra bra underneath!

i LOVE this sports bra! I am a 34dd and have lost about 60+ lbs so you can imagine how hard is is to find a bra to support lose boobies. I tested it out for my kickboxing class and it was great! I was very comfortable and didn't worry about adjusting my bra at all during the jumping jack drills and the standup+quick pushup spurts. If I feel like I need a bit extra support, I will wear a soft cotton bra underneath. This bra will also make your chest look much smaller. It gives me a more flatter & boyish appearance but I don't care. I'd rather have the girls in place than moving everywhere. I highly recommend this bra and need to order another!
