Have you ever used a personal shopper? If so, what was your experience?

I hate shopping for clothes with a passion. I’m thinking of using a personal shopping service at a department store.

If you have used one, were you satisfied with the help you received? What was the cost? Did you believe that the shopper chose things that were right for you or was it about his/her commission? (I assume they get commission.) I have a terrible time picking out things for myself and could use some help!
