At work, we have to dress up for Halloween. The problem is, this year I will be pregnant.
I don't know what to be for Halloween, now!
Everyone at work has done the pregnant nun, but 2 years ago some actual nuns came in and left us a bunch of church cards & stuff so now we just don't do that... we don't want to offend people.
I was 8 months pregnant during Halloween a couple of years ago, and I went as a hippie because the free-flowing shirt was the only one that would fit that wasn't maternity! I don't know how far along you'll be or how self-conscious you are, but you could paint something on your belly and dress up around that. I've seen targets, smiley faces, jack-o-lanterns, etc.
Here are a couple of links I found real quick:
I had 2 friends that happened to be prego during halloween (few years back). One went as a banana split...her cute bump was a different flavor of ice cream. The other one went as camel...she wore a brown body suit and sewed a large stuffed camel to her back (after cutting the hump off, so it looked like she was upside down). It was pretty funny. Sounds like fun at your office.
The trend around my neighborhood has been to paint jack o lanterns on their bellies... but if this is for work that may not be great advice. My pregnancy over Halloween I was too concerned with Katie's first Halloween, so I pushed the stroller (just incase of a breakdown) and held the camera.
