Halloween // I like costumes that change over the course of the evening, any suggestions?

Some examples I've done include "chia pet Abraham Lincoln" which had a hat with fake grass that grew over the course of the evening and a fake beard that also got greener. Or the "This is fine meme" where I had a ton of paper fire pieces that I put up all over the party as the night went on so the entire party became my costume.

Have y'all done anything like these or have any suggestions for anything similar?
