I'm a newfag when it comes to fashion so go easy on me if this store is well known for being shitty.
I used to work at one of their stores. It's all ugly, overpriced garbage, especially for the girls' clothes. I've seen the same "brands" on sites like overstock for something like 80% off. For guys it's not as bad if you're into skate/street shit, but if you're not in high school or at the very latest, early college, you'll look like a tool. It's just a bad idea, even if the shit is on sale.
