Were there any middle-aged men dressed as Sailor Moon?
Not this year, not that I saw. There was one bad male cross-dressing cosplayer but other than that I didn't see any particularly hideous sights from guys. Mostly just girls.
Heh, we saw some guys like that at AnimeBoston. Some VEY strange looking folks, but apparently very well behaved, according the the concierge at the hotel where it was held. He said the S&M convention the previous week was kinda wild. ;o)
