Costume Fairy Adventures is... well, its about fairies, who wear costumes, and have adventures. Ok that's not ALL it is, but that's a good bulk of the game, CFA is a fairly rules lite and simple system for running games about whimsical fey getting into weird shenanigans using weird costumes they made or found lying around, character creation and gameplay are both very simple, and this game is a biiit more niche than my usual spotlights, but I guarantee this one's good.
