I don't know why, but this costume idea made me laugh so hard!!!
All you need are two sweatshirts (one white, one black) and two bottles of fabric puff paint (one white, one black).
Squeeze the bottles over the sweatshirts to spell out "pepper" and "salt."
Let these dry and you're costume is ready!
you may not win any costume contests with this idea, depending on how "sexy" you can make it for the gals, but it's the easiest thing to make ever!
