What are some original halloween costume ideas?
I’m 15 and I need some original costume ideas. 
Nothing slutty though. And I don’t want to be a real person (ex katy perry, britney spears…)
I’m about 5’1 and I have red hair if that has anything to do with it.
Since you have red hair i would recommend poison ivy or harley quinn but if You want originals
A zombie
a vampire
a princess(ew)
a werewolf
a circus member
skeleton
If you are crafty and want to make your own costumes, buy Martha Stewart’s Halloween magazine. She has some great costumes ideas in there. Or, do like my daughter – she collects Living Dead Dolls – they have a contest each year for people to dress up like their favourite doll. http://www.livingdeaddolls.com/lddsite.html
If you’re not into homemade costumes, check out buycostumes.com – they have so many costumes I am sure you will find something.
Have fun!!
Be a pirate matey! An Elizabeth Swann pirate costume is a great idea.
