I am a preschool director and I can't figure out what to be this year

Thought about getting one of those skeleton w/ baby skeleton shirts but I am not sure yet.
I can't think of a bigger waste of money then buying a maternity Halloween costume.....but regular stuff clearly won't fit over the bump!
Would love to hear what you all have planned this Halloween!
I searched, but didn't find anything as a previous thread.
Re: Halloween costumes...have we done this already?
I also have to dress up for work but I'll probably just don cat ears.
ETA: hmmm the link disappeared. I can't figure it out

I work at a high school so less is more. I'm thinking of wearing black pants and a black long sleeve shirt. Because I'll have a bump, I will tape a number eight to my belly.
Simple.
