This Avatar costume is super popular and if you have the body for it wear it with confidence to a costume party and you will get lots of attention!
If you want a really dark and deathly type of costume go with a Gothic Seductress or a Vampire costume.
Here's a really cool idea... Go as a Rockabilly Girl and wear a 50's retro outfit! The Rockabilly look and Pinup girl look is very hot right now!
If you would like to dress as a rock star you can get a really cool 80's Rock Star Wig or you can be a Hot Rock Vixen!
