The band is altered. So now the bra fits closer to 30F/28FF ( but for my fuller days it's small). The cups give not perfectly smooth look. I'm not sure if this bra gives enough support for running or jumping. I prefer yoga, and this bra is very comfortable for this kind of activity. I highly appreciate J-hook , as this gives additional security that the straps will stay on their place.
The band is definitely too big, but the cups are good for me. I've bought it just because of a good price and my sewing skills. I'm going to shorten the band. This bra is really very similar to the Panache underwired sports bra. But I could not buy Panache because of the size issue: 28ff was too tight for me and 30f was too loose.
