Well you are only 15 so might save the sexy stuff until you're like 17 or something, plus no one really goes scary anymore well I guess that's no totally true we have a guy who dresses up as an undead clown and chases children with an actual live chainsaw ( without the chain on it but still ) every Halloween but other then that I don't see much scary stuff.
You're thinking of Halloween already? It's not even freakin' Labor Day yet. Slow your role. Personally I think women tend to do sexy on Halloween, too much. They know it's the one day of the year they can get away with looking slutty without actually being called a slut.
I think American Hallowe'en is lame, but I think it's lame we don't make more of a deal about it here in the UK because I love hallowe'en. I don't get what's hallowe'en about sluttly nurses or slutty policewomen, or slutty cats... it's supposed to be scary!
