I'm amazed so many of you are saying Aeropostale! It's very "out" around here. Nobody shops there at all.
American Eagle and Hollister are definitely still in although my DD17 doesn't care for their stuff so she doesn't go there.
She likes Charlotte Ruse, Forever 21, Wet Seal and some other smaller stores with cheaply made clothes like wet seal.
I don't think Coach or Vera Bradley are popular here. Or north face either.
Uggs are very popular but knockoff are also totally acceptable, even the cheap ones. No problem. I guess because we're in FL and there's not much of season for them.
Platos Closet can be hit or miss. It's definitely worth a shot.
DD has had luck lately at Bealls outlet and Burlington Coat Factory of all places, she just stopped in and found things she really liked.
I agree about just picking up one or 2 things and waiting a week or so before the big shopping trip because she'll know more of what she wants once she's seen how the other kids are dressing.
