Being a Ghibli fan, I have to say I love your Baron costume! How's the head made? As for cosplaying, well, why the hell not. I used to wear costumes in theatre college as part of the costume design/interpretation department's annual display. It's not something I'd personally do for fun now - although I did have a female friend who walked around Wimbledon in 18th century dress, which was hilarious - but I've got respect for people who throw caution to the wind in pursuit of a good time!
Unless you're a furry. *shudders* In which case, keep it to yourself!
btw lol nice bandwidth steal message there on the second one.
