Many companies offer unisex shirts for women or else their women's shirts are just too big. This shirt, one of my first purchases here, fits better than most. It's a small but is neither too wide nor too long. Would have preferred XS but it looks like that size has been phased out, unfortunately. I did get one on sale but it doesn't seem to be much smaller than this shirt in size small. The fit is a regular fit t-shirt, not a slim fit. I'm 4'11 and 80 pounds and wear either XS (when available) or small.
