This bra has a bit of underwire support in it, and seems to provide a bit more shape than a typical uniboob sports bra. I was wearing it for running and the bottom band around the ribs is comfortable, it's easy to get on and off (even when sweaty), and you get good coverage up front. I was still a bit bouncy until everything settled into place. I'm about a 34B-ish. I bought a small.
