First, the sports bra is really beautiful. I don't think it would offer great support for bigger cups, but for smaller cups it works well enough.
The fit is a bit strange for me (size: M, 167cm, 53kg). It fits snug over the bust (cup size 34A), but the underbust could be tighter. The armholes are really small, but this could be because my shoulders and back are very muscular).
But the biggest problems with this are the really really bulky seams underneath the arm. Too many layers of fabric are hunched in one serger seam. This gets really uncomfortable in a short time.
Sad, because otherwise this could be great.
