Halloween Costumes

So every year I'm really into Halloween, I love the candy, decorations, scary movies etc. etc. But when it comes to the costumes...it is always a challenge on what to wear. There are a lot of options of course. It always takes time to put it together as well. If you leave it too late and then go shopping for it, there isn't much left, so you need to get on top of it early. I also enjoy costumes that are thematic with other friends i.e. a group costume. But here is the thing that seems to happen every year that I never understand......why do all these girls out there use it as an excuse to dress totally skanky...what's up with that!!! This isn't a party with just you and your boyfriend in your bedroom....Hello, you are still going out in public Ms. sexy nurse, french maid or little devil. I don't get it at all. I know this is a page straight out of the movie Mean Girls when Lindsay Lohan's character shows up to the party dressed up as a dead bride and is all scary and everyone makes fun of her. But seriously how did Halloween turn from scary to slutty???I want to bring scary back! (not sexy...) anybody with me???
