Party themes for 13 year old?

Here's a few ideas. 

HOLLYWOOD:

Invites- A microphone or something fabulous saying Your Invited to ______'s Fabu Hollywood Party! Dress up as your fav star! 

Decor- Glitters, sparkle and shine! Plus, a red carpet and maybe a premier movie theater? 

Food- As dinner, you could bring your friends to your favorite restaurant! Snacks could be: Cupcakes, popcorn and candies. 

Fun- Everyone has to do what their star does, for example if you are Lady Gaga you could sing Born This Way. Dance party, karaoke, modeling, photoshoots are all cool. Another idea is having Star Stations. Like you all could get manicures and makeovers from a spa or do each others. Then you could have a dress up station, a photo shoot and at the end of the night you all can rock out the stage (or your dining room table) and the red carpet by singing or dancing :). 

HAWAIIAN:

Invites: A coconut saying, Aloha! You are invited to come join the luau party for ______! 

Decor: Blow up palm trees. 

Food: Fruits (mango, pineapples, coconuts...), hamburgers and regular snacks. Make your own smoothies would be coolio. 

Fun: Dance to Hawaiian music. Limbo. 

GAME SHOW

Invites: A phone call (call their house) and having a host voice saying "You have been invited to play the Birthday Bash game!" 

Decor: Set up each room as a different game show... Except for your bedroom of course. The living room could be Are You Smarter Than A Fifth Grader, the basement could be Minute To Win It, the dining room could be Wheel Of Fortune and so on.

I hope I helped! You can email bluerapper5@yahoo.com for more ideas from me if you'd like.

A movie night - not horror movies necessarily but chick flicks and whatnot or whatever movies you're into.

You don't really need a theme to a party. Or you could do a mix like movies for some of it, make up and hair for some of it, doing nails, etc.

What about Hawaiian?

Cavemen :D
