Based off the storyline on Fiction Branches of the same name originally done by The_Guest. Here's a link to the original story.

100GPs for additions while supplies last(and they have to advance a storyline, not just adding more choices)
How it works is, it starts with one person who will go and put on someone else's clothes and once that happens they and everyone else thinks they're that person except with their original first name. Once they have taken a new identity, they will begin to gradually transform into that person physically and once they have completely become that person, their first name will change if needed(such as gender change). When they put the clothes on, the person who's identity their taking goes through the same thing and goes off to find a new identity of their own.
Rules
1. Everyone(including the person themselves) must believe that they are the person that they are dressed as and treat them as such.
2. Changes must be gradual, nothing instant
3. No body swaps, this is a process description story.
4. When someone becomes 'identityless' no one can see or touch them until they find a new identity to take.
5. When a person fully physically assimilates into their new identity, they take on a new name different from the original person who held it.
6. Have fun :)
Age and race change are encouraged.
Costume Shop Rules:
Decided to try something new with this. In one of the branches I threw in a costume shop that has costumes of various video game/tv show characters. Special rules for that include the following.
1. When a person puts on the costume they are transported to that character's universe and take their place.
2. When they arrive in said universe, they are still physically themselves.
3. Since they're popping up in a new universe, there is no new replacements, just them becoming that character.
4. The person actually becomes a pixilated cartoon character. Not a real life version of the character.
5. The rest of the regular rules still apply
