The best inexpensive Halloween costume for me?

I am seriously bad at choosing halloween costumes. I don't want to spend a lot of money, preferably under $30 but I'd go to 60. I'm 5'3" 103lbs, long legs (I look better in skirts than pants), medium-light skin, long black hair with side-swept bangs. I don't want to be anything like the wife of frankenstein or eve like everyone else does. Nothing skanky either! I've already been a vampire, cat, devil and geisha. Ideas? Pictures would be a super help.
