I have several in this line and this was easily two sizes smaller than usual. The funny part is another part of my order in the same size was comically too large. Sizing clearly isn't a priority right now. Definitely size up here.

COLOR: I REALLY love the mauve color. STYLE: Not too crazy about the collar but could deal with it for good price and if overall size worked. The pockets are open and do not zip like you normally find on athletic wear type clothing. SIZE: I generally wear between a Medium and Large (10-12). I ordered the medium and it is super snug when zipped up. I would recommend sizing up, at minimum, 1 size. If you want it to be loose consider 2 sizes. MATERIAL: Very soft
