Costume

I was able to leave work on time today and shop at the local costume shop for our upcoming Halloween costume party that we are having. It was so much fun to go "shopping" and try on the different outfits. I went in the store with one outfit in mind and came out with a completely different one. I'm not going to reveal it until closer to Halloween, but my "pic of the day" is a portion of that costume.

Any guesses as to what my costume is?
