This is a Chacott French sleeve T-shirt. It has a small pocket on the chest with a butterfly embroidery. (The pocket is more for design than for use) I used to wear it for yoga. Although it has a generous width, it's a French sleeve T-shirt that makes you look slimmer thanks to the shirring at the armholes. I wore it often, so there is some pilling overall, and I'm selling it at a lower price. Please consider this before purchasing.
