I got these for pole dance practice. I usually wear size 2-4 in bottoms, and I got the small/medium. They sit well and are very flattering, considering the amount of exposed skin. They also stay put and cover what they should consistently, so you wouldn't need to worry about accidently flashing anyone while waving your legs around. My only complaint is that the fabric is not particularly comfortable, especially for the nether regions (I'd say it is stiffer and more abrasive than most swimsuits), which makes them suboptimal for wearing to regular practice.
