What Not To Wear??

What's a 37 week pregnant girl to do for Halloween?? Do I go with the old cliche and dress up as a nun? Do I spray paint a box and cut out the front and go as a "bun in the oven"? There's not a whole lot of available options considering I'm not of the mindset of "Sexy {fill in the blank}" like the unmarried, minus children, sect! I mean seriously?? I am not going out in that!
I'm taking my 2 year old trick or treating (Or Trick or Trina (our cat) like Natey likes to say) and I could just bone out and not dress up, but where's the fun in that? I have thought of some semi- cop out costumes. I could just applique some orange felt onto a black shirt where my belly is and make a jack-o-lantern face or dress up like a cat and cut the belly out of my shirt and paint it like a fish bowl. I need some help here. I don't want to spend a ridiculous amount of money on a costume. I'm thinking 20 bucks here people. So give me your suggestions. I am not easily offended so don't hold back {Ahem, Nikki}.
