Okay, I want to hear everyone's Halloween plans! Last year I did NOTHING!

This yr I am attending several parties, doing a ghost tour in Galveston, haunted houses in Houston, co hosting a party as well. We like to stay in a couple nights before the 31st to carve pumpkins together, listen to the Halloween Pandora station, watch scary movies.
I have nooo idea what to be though. For my bf we figured he can be a Mad Scientist. Since he was a molecular and cell biology major, he already has the lab coat and goggles. we want to spice it up more maybe...he has the round glasses and we can make his hair grey and use a comb to make it even bigger (He has long corkscrew curly hair.)
No idea what I am going to be though....I'm past the point of being anything "humorous", or cutesy, and I am too chubby to be anything "sexy" (no one wants to see that!) So idk. What are y'all doing for Halloween? And any tips to spice up a mad scientist costume?
