If you have the tools you need to get the tags off, it's easy. For me, it's 50/50 if there is someone counting. Just wait or if you cant wait, get a jacket and put a shirt, pants, etc in the jacket then zip it up. From what I've experienced they've only ever counted hangers, given me a little sign with the number on it, and that was it. Also many of the forever 21s are 2 stories, walk to the other dressing rooms and see if they are unattended. More than likely there is at least one that has nobody counting
