Nice sports bra -- fabric is soft and stretchy and it has more than enough support for running (I'm small-chested).  Not giving it 5 stars because it's not really seamless -- true there are no side seams -- but the edges are tucked under and stitched around the edges of the scoop neck and arm holes.  Haven't worn on a hot-weather run yet, so I'm not sure if these edges will cause chafing, but I suspect they will based on other sports bras I've worn with the same design (in which case, I'll wind up wearing it inside-out).
