Makeovers
Invite the girls to bring their own makeup or offer any old makeup you may have. Set up a five-minute timer and have the girls pair off and perform makeovers on each other. Alternatively, they can perform makeovers on themselves without the use of a mirror and see whose comes out the craziest. Have everyone vote on which they find the funniest, and let the winner choose which game to play next.
Nail Polish Hot Potato
Have the girls sit in a circle and pass a bottle of nail polish while some of their favorite music plays. Stop the music randomly and the girl with the nail polish must paint as many toenails as possible until it begins again. You can also switch the color of nail polish halfway through so that the girls will end up with multicolored nails. The girl with all her toenails painted first is the winner.
Blind Date
Have the girls sit in a circle and give one a heavy piece of paper and a pen. The first girl will write a boy's name on it and fold it over to cover it up before passing it to the next girl. Follow it with a girl's name, then a place, then a comment that the boy says, followed by a comment from the girl, ensuring the paper is folded each time. Have the hostess read the final product out loud.
Lips on the Poster
Find out the common celebrity crush among the girls attending the sleepover. Buy a nice poster of the guy and supply a bright colored lipstick. Each girl should apply the lipstick and be blindfolded, spun around, and then told to kiss the poster. The girl who comes closest the guy's lips wins and gets to take the poster home with her.
