It's less than a week until Halloween and you're still without a costume. And without money.

Now that's scary.

But no fear! Make these 3 easy Halloween costumes on the cheap with things you already have tucked away in your closet.

1. Michael Phelps: Skip the swimsuit and put on a pair of windbreaker pants and a jacket-- red, white and blue if you can pull it off. Slap some goggles on your head and dig out those old medals you won in elementary school (or make your own with aluminum foil and ribbon). Voila. You're an Olympic superstar.

2. Ghost. It's an oldie but goody. You're never going to use that old white sheet in the linen closet anyway, so you might as well poke a couple of eye-holes in it. Bonus: You can use it as a blanket if you're outside and it's freezing. It's like a Halloween Snuggie.

3. Well-Read. Yep, I'm a bookworm and a dork and this was my last-minute costume for a holiday party at a friend's house a few years back. I carried a pail (I was a well) and wore all of my scarlet clothing (I was all red). Very punny, I know, but also very easy.
