The ghouls had all been invited to a ‘ball’, or as modern day people say ‘important party.’ Sodo wore his only suit, which was a pretty normal looking one. Swiss wore a dark red velvet suit with a matching black tie. Rain was matching with Sodo accept he had tassel near the chest area. Phantom wore a basic suit and was matching with Mountain, and the ghoulettes all wore matching red dresses. You were going with them as a ghoul/ghoulette.
