I love aeriopostale. I have way too many things from that store. But either way, you can't deny that this store is awesome.
Okay, it's not ENTIRELY "in", probably and sadly because of its low prices (dangit!). Yup, girls these days can't have it unless it has the potential to force you into sever debt. Well, of course.
Aeropostale is a great place to get the essentials though. Like a jacket, or a tank, or maybe some shirts to layer. I would NOT however, advise you to splurge there. Buying their screen tanks is not a good idea. You'll look at it the first time and go "aww, it's a monkey!!" and then after 50 or so shirts with the same stupid monkey on it, you get bored. And sad. Tear.
I also noticed that aeropostale tends to stay a beat behind in consideration with fashion trends. Therefore, if you buy from aero, you want to buy stuff that'll make it through fashion fad-extremes -- nothing flashy, nothing outstanding.
Oh hehe, I forgot to mention that I'm a clearance sale shopper....so this review might be slightly biased. Who doesn't shop clearance....? Okay, bad question. Whatever. Aero can STILL be expensive, especially on their super new merchandise. If, in the case that you DO buy the super new merchandise, then you're probably successfully staying on the "in" boat along with all the other designer name brand clothes.
Other than that, try not to get sucked in by Aero's massive sales, as tempting as they are. A dollar is still a dollar and if you're thinking of buying something you might not wear, don't buy it.
One more thing, I suggest going to the AZ mills location rather than the Chandler mall one, simply because the AZ mills one is bigger and has more sales. *shrug*
