This bra is magical. I've been searching for a soft, supportive, non-itchy seamed bra and this is it. I was leery at first because it looked and felt small going on, but it fits PERFECTLY. It's maiden voyage was on a hot trail run (lots of sweat and dust) and not only did this bra not budge, chafe, or turn into a wet dish rag, but I did not want to take it off when I got back! It is that comfortable. I am a 36B with swimmer shoulders and breast that fed 4 babies (so forget about a round cup size, I am a "long" cup size) and there are no fit issues. The fabric is soft, any edged are rounded and no irritating seams.
