Now I'm dead set on getting this shirt, so you could imagine what I felt when I saw it was zipped off my cart since it was sold out in a guy's small. I'm still interested in the shirt, so much that I'm thinking of buying either an XS(2 inches less in width, 1 inch less in length) or buying a girls large( the sizes seem to be almost identical)

My question is that am I better off buying an XS or buying the girl's large? Is there a difference in terms of cut between the girl's and guy's tees, or would the small and large be identical?

Here's a link to the size chart:
