I'm quickly becoming a Born Primitive junkie, but this is the first item that I am returning. The fabric has a lovely soft and stretchy feel, and the length is good, but it's cut just a little too generously in the midsection for me - it definitely did not look on me how it does on the model. I prefer my tanks to be pretty form-fitting so they move with me and don't swish around, especially since I am a profuse sweater, and extra, sweat-drenched material just annoys me when I am moving. I ordered my usual size S (I'm 5'10", 140#, 33/27/39 and fairly lean) and I think that it's the right size, but there was extra draping across my ribs and stomach that didn't feel great and wasn't flattering. Still giving 4 stars and recommending because clearly the majority of people love this tank.
I have two The Edge tanks in S and those fit me well - not tight right against my skin, but not with the excess material I felt this tank had.
