What to be for Halloween...

I am thinking of dressing up for work tomorrow--we have this big party at 2:00 and a lot of staff (and residents) dress up. The residents then judge the costumes and pick the winners--it's really cute.

Anyway, I am trying to be simple here. I'm not going to go out and spend a lot putting a costume together. I thought maybe I could be a pregnant witch? I just need to wear a black maternity top and pants, my mom has a cape, I need to find a hat, and I have a broom I can use. I also thought about taping a little skeleton on my belly to represent the baby. Does this sound like a good idea?

Yays, nays, and any other suggestions welcome!
