Fakku at Otakon?

Oh my gosh. I was at the dealers room at Otakon 2015 (Baltimore) yesterday and one of the dealers was wearing a fakku shirt and made my day selling me an alpaca plush. Today she wore a bathing suit, and it wasn't a "hentai exclusive" vendor area, so I'm not sure if it was official or anything. (I didn't dare ask!) But I was happy regardless!
