This tee is more fitted in size, so size up if you want more loose-fitting. I purchased my normal size S (S-M, 6) and it is the fit I was looking for which is not oversized. The material is nice, something to look for given the price tag. I was in search of something casual in this particular color blue to match a pair of pants. I liked purchasing from and supporting this small company. They sent a personalized note in the package. Shipping was fast. I expect some of the popular sizes to sell out.
