Got this idea from a bit of fun some friends of mine have been having.
The idea is this:
You pick one of your OCs, and draw them in the outfit of the OC above them, then the next person has to do the same thing with your OC. Make sure to call dibs before your do so.
Make sure to post a reference for your character, both in their regular and swapped outfit.
I'll start with my boy Crypto.
Issue is, Crypto only wears a trench coat and matching fedora, nothing else.
You can just get around this having the OC in question wear a purple shirt and pair of shorts underneath, or you can have fun with what they wear underneath, doesn't matter.
