I'm a female who normally likes the fit of men's small t-shirts because they tend to have the higher crew neck that I like.  This t-shirt was not ideal for me because I am, unfortunately, somewhat wider in the hips than in the shoulders.  I know this would look great on a man or a woman with narrower hips.  It's a nice light fabric, good crew neckline, so I'd still recommend it even though it was not perfect for me.  So then I ordered the medium and it was an improvement around the hips, but then the upper body fit was not quite as nice.  I'm still keeping both shirts and will wear them and will try to reduce my hip width or build up my shoulders!
