I'm a 36B (size does matter in choosing a sports bra). I decided to try this in the dressing room when I saw the "360 motion" tag. It went over my head without too much difficulty but when I tried to fasten the hooks in back, it became a major battle. I ought to subtract 1 star for that. 5 minutes later, I managed to fasten it and did a "bounce test." I was impressed. I bought 2 and gave them a real test run in my 40-minute circuit workout and 2-mile run. They're the best I've ever had - even better than the $60 sports bras I got from my local running store, so they get 5-stars. There's no bounce nor any show-through. Way to go, Champion!
