Must custom badges be PG? (nevermind, found it)

I looked for some rules list on the site that might have this but didn't see it.

Rooboy http://www.furaffinity.net/user/rooboy/ had the thought of a mature themed conbadge. I was wondering if wearing something like that would be absolutely banned?
Personally, I'd love one, but I would expect that badges worn in public or even the main parts of the convention would be required to be PG or less.

Okay I'm rambling.
Bottom line, can you wear a mature/sexual themed badge?

-EDIT-
found it.
"Attendees, when in public areas, may not wear clothing which is overly revealing or inappropriate to the atmosphere of the convention."

dang. :/
Oh well. =3
