I am a teen myself and have great fun planning things, like my birthday parties. Well my idea is a model runway and after party.This party should be held at your house. What you do is you get the girls to bring some of their best clothes,make-up,and hair stlying things.You(the parents)put together a runway of pillows, and have the girls bring their own up-beat music to walk to, and of course the parents should leave while the girls have their fun. You set up a area near the runway room with a bar-top,I found that a short bookself works as long as you cover it up with something that will go with the theme. You supply the "bartop" with plastic champagne glasses,sparkling cider in differt flavors,clear soda,and a bucket of ice. Have your daughter serve the drinks to her guests. This works alot for teens who are from 13-18. Have fun and good luck!!
