answer:I shop there regularly, in-store and online, and sometimes their sizing is a little wacky or inconsistent depending on the particular design. But pretty much all my stuff (lots of tee shirts and hoodies) is XS and fits more or less perfectly. I would say that the hoodies with zippers tend to be a little bigger by design than the pullover hoodies, however, so you might want to take that into account. I’ve never worn a wholesale item from AA, though, so I don’t know if that set of items is any different than their other stuff when it comes to sizing. Probably not.
