I was a bit skeptical of a sports bra with underwires, but it's been great! Things just don't move with this sports bra.  I'd never actually realized how much things had been moving before until I tried this bra and they...weren't.  Adjustable like a regular bra with hooks in the back and adjustable straps. The cups are shaped so the wires are a bit further out than in a usual underwire and aren't poky-I really don't feel them at all-it's very comfortable, actually, and seems to do a fantastic job on fighting bounce.  The look under a shirt is very flattering as far as sports bras go-high and separated, which is a good thing since this is not a great sports bra for wearing without a shirt-the front looks a bit odd, but more importantly, the back has an obviously lingerie look-not ideal if I were wearing this alone.  Given that I do wear a shirt anyway when working out, that doesn't bother me much.
