Why not go to the interview dressed in the all black outfit you would wear to the job?

I'd tell them you really like make up and trying out different brands. You read fashion magazines and stay up on trends.

You are friendly, always acknowledge and approach customers, listen to their needs, suggest they try new things, are enthusiastic, etc...

They want to know you are honest and reliable, a team player, friendly with the coworkers and respectful of the manager, etc...

You pay attention to detail and would make sure the stock is always replenished.

I remember you did have an incident at Wal Mart where someone broke into your locker and stole your money, right? You could tell them how you handled that, if they ask. Maybe you will say that is partly why you left there.
