The band seems to run pretty tight. Stretched, my 32G only reaches 31.5". The cups are also a little wide for me and there is empty space on the side. I've worn it a couple times but it just doesn't fit right. On the plus side, the fabric is very comfortable.
It fits pretty comfortably but starts to poke under the arms a bit after wearing it all day. The band stretched out a little bit but not too badly. The material is really comfortable. Would look best under a T-shirt.
