This store is a mess. Chaos is the best way to describe it.
I actually like F21 clothing enough - I've purchased online a few times and that's the way to go (free shipping over $75). The clothing is better quality than say.. Garage Clothing or Stitches, but nothing to rave about. Very trendy, too. You will probably only get 1 or 2 seasons' wear out of them before they go out of style.
The lineups at cash and change rooms are ridiculous. There aren't employees to help you around the store, because they're too busy cleaning up after everyones mess. People treat this store like an absolute dump. Women can be nasty.
The layout of this store is weird. Who wants to climb stairs while shopping? I know this makes me sounds lazy, but... anyways. Also, its completely disorganized. If you find something you like, good luck finding it in another colour, let alone your size.
