I'm not sure about this one. So many raves about this top, so I ordered 3 colors and I have to say the fit isn't flattering. The cut is long (and I have a long torso) which is good, but this is really long so that it bunches up around the top of your hips. Arm length too....would fit a gorilla. I don't know if sizing down would help because it seems cut smaller in the shoulders and wide in the waist, which is the opposite of what I need. This fabric seems to highlight every lump or bump, so you can't really wear anything underneath without it being magnified. I don't carry any extra weight in my torso, and don't have this problem with other very tight shirts, so it's perplexing. Seriously, I think it even shows goosebumps! I can't attest to the performance because I can't decide whether or not to send this back. The fabric IS butter soft though.
