I love these little french toast shirts. This shirt fits normal, but some other thermal shirts run larger. Although it's a bit pricey, I'm willing to spend a few bucks more for good quality. Apparently, other buyers agree, as this brand often sells out. Based on my experience with this brand, if it's in stock and available, buy it; Otherwise it may not be there when you search again.
