Pros
Generally fun and enjoyable work environment. As a fan of the clothes, an employee discount was nice. Non-commission pay lead to much less "in-fighting" and competing against co-workers. I now fold my laundry exceptionally quickly and neatly. If you're up for it and show an aptitude, there are some more interesting things to do in store such as merchandising, mannequin work, etc which are a welcome break from customer service.
Cons
Limited earning potential due to non-commission payscale (Minimum wage. But, then again, it is simple clothing retail so that's pretty much expected). It's clothing retail, as such, you learn to dislike customers in general due to rudeness, cleanliness or a multitude of other reasons. Vacation blackout days and requirements to work on heavy shopping days (ie, boxing day) sometimes coincide exactly with when a student would be able to travel/leave town to visit family etc.
