Elle, you can phone either AGPNY or AGPC and find out if they still have any of the Star Flower Outfits. You are usually connected with a PS. I don't really think it matters about your age - you pay for it with a credit card which is what I assume you do when you order online or over the phone. It's really not that different than ordering anything else.

P.S. Don't forget to ask your parents!!!
