Aeropostale (aka Aero) is a pretty awesome store overall. They have pretty nice clothes at super cheap prices. Some of their clothes resemble Abercrombie or AE clothing, such as the 3/4 sleeve polos...and quite frankly, there is no difference between any of them! Except for the fact that it is a lot cheaper.
The sizes at Aero are kind of funky though; however, they're now making 'slim fit' clothing that are long and skinny, which is great. (They used to be wide and short, which my friends and I just could not fit.)
Beware of the hoodies/sweatshirts from that store though. You're better off buying an Abercrombie one, since those..after washing them like 2 times they become this thin ragged piece of cloth. Shows that sometimes, overpriced clothing can often be better in quality.
Workers at Aero are also extremely helpful. Prices are great, the quality of the clothing is pretty good, great store overall!
