Yep....Abercrombie sizes are small. Eveything is a very slim cut same goes for the adult store. My DD prefers Hollister....the clothes are exactly the same and much cheaper. Plus, the cut is still slim but not as much as Abercrombie.
My DD is 14 and wears a 00/0 pant from Aeropostale so she is rather happy that Aber and Hollister are slim. She wears a L-XL at Aber and a XS-S at Hollister. She can't buy pants at Aber because kids pants are not as narrow in the waist as junior pants. They do, however, have the most awesome soft jeggings that fit well as they are totally stretchy like a legging.
