Pregnancy Halloween Costumes

I am officially 6 months pregnant and sporting a very obvious basketball sized baby belly :) This is my second pregnancy but my first Halloween with a baby bump. We are hosting a Halloween party for my 3 yr old and I am looking for some pregnancy Halloween costume ideas. I have seen a few ideas on the internet and I think unless I see something cuter that I will be making myself a Mike Wazowski costume, you know the green eyeball shaped monster from Disney's Monsters Inc. :)  I would love to hear what my fellow pregnant mamas will be wearing for Halloween or what you have worn in the past.
