Jessica Simpson in Dukes of Hazzard

Looking for an inexpensive and sexy way to get noticed this Halloween? Look no further than a pair of super-short daisy dukes and unbutonned blouse. Everyone remembers the attention Jessica Simpson got from her role as Daisy Duke – and any excuse to wear short cut-off shorts and cowboy boots is good enough for us!

Michael Jackson in Thriller  

We’re pretty sure this is going to be a popular choice for several men (and, who are we kidding, women too) this Halloween but the traditional Michael Jackson costume can be transformed with this deluxe replica Michael Jackson Moonwalk Thriller jacket. Look like the king of pop this Halloween and all your friends will be green with envy.

Britney Spears in Circus

Want to look provocative in a subtle and unique way this Halloween? We suggest being Britney Spears from her Circus tour. The blue and red buttoned jacket will keep you warm while the pleather short-shorts and fishnet stockings will give you the sexy look you’ve been waiting to rock since November 1st of 2008.
