By "apparel" do you mean like the dorky Contest/Musical accessories from the actual games or just generic silly hats and stuff.

let no one say this isn't a serious rp about serious things I'm going to wake up wondering why I asked this question in the first place

edit of edit: Actually this is a stupid question because I just checked the list of actual accessories/props and they consist of way fewer actual clothing items than I thought. Super Contests were a very strange event in Pokemon's history...
