This was exactly what I was looking for, so I just bought a few more colors. The fit is body-hugging. It isn't as tight as a full spandex compression shirt. But it does conform to your body, just like in the picture. It is very lightweight, so do not expect this to be much of a warm base layer for extreme cold. Works perfectly as lounge wear when worn with pajama pants, or as a casual top with jeans
Other reviews said the sleeves were too short. I got a medium and it was a normal USA-size fit.
