Once I finally have an actual flat and job, I'm gonna start a thing where I invite all my friends over for dinner. And there's gonna be a dress code but it's just "that one outfit you never have any chance to wear". Flapper dress? Awesome. Medival gown that you got at a renesaince fair but don't actually know what to do with? Yes! Prom dress? Of course! Cosplay you made for that one convention? Definitely. Pikachu onsie? What would be more fitting?
