the fabric is light and extremely soft. It was thinner than I was expecting, which is probably good for working out (haven't worked out in it or washed it yet). Decal is beautiful. I'm a 36A/B and 134 lbs and the medium fit well, but was possibly flowier/bigger than I'd like. Hard to say without comparing to the flowy in the size small, but just be aware the arm holes are indeed pretty big.
So comfy. So awesome.
I received this in my mystery tank package! I was so surprised as this was one of the shirts I had wanted. It is so soft and perfect for working out. So glad I ordered this! You definitely have to wear a tank or sports bra underneath as the sides come down pretty low
