Pros
The 20% discount is better than nothing (although many other stores provide much more!). You get to work with fun people who enjoy fashion. Managers are usually very flexible if you need to work around a school schedule or personal plans. I worked there while i was going to school and was able to tailor my schedule to fit with my department's needs and my schedule. Also if I needed a weekend off to go skiing, if I requested it far enough in advance, there were usually no problems in getting it. As a full time employee, benefits are also nice.
Cons
I am so exhausted of having to work nights and weekends. It gets really hard when all my other friends have nights and weekends to hang out or go skiing and i have to constantly work. Also, business can get really slow after the holidays. Commission is great around thanksgiving to new years but in january to march it drops off a lot. My hours in january were close to 35 hours per week and got slashed to 15-20 in february. this causes your paycheck to be pretty unstable. also, if you work with people who steal sales and are too competitive, it can be aweful.
