I like some of their stuff. I wouldn't buy their graphic shirts. Or most of their shirts.
I don't think their clothes are anything special though.. You could find the practically the same things at Pacsun, American Eagle obviously, Hollister, Abercrombie & Fitch, Urban Outfitters, Forever 21.. and more..
I did see this one cute white, strapless top there. It was 50 or 60 dollars. I wouldn't have paid that much for it. But it was cute and delicate.
Yes, they look good. Thing is though, do they make you feel like the young woman you should be? If they make you happy and make you feel stylish, then great. If you're going for what others think of it you need to start pleasing yourself more :) Just try this: look yourself in the mirror every morning and say in a firm voice 10 times, "I am beautiful just the way I am" and see if that works for you :)
They do look good, though, at least from a 16 year old guy's perspective :)
