Heres a good costume idea for a Medieval Times Princess:
First find a long red skirt. Next a red or tan peasant shirt to match
buy or make one of those round crown things with a vail in the back.
Put your hair into a 1/2 up 1/2 down and put the crown onto the top of your head. Get tan high heels.
When you put it all together wear pink lip stick and blue eye shadow, you'll look better than your friends!
Thanks to Tori for this great idea!
