Ren Faire rules question: gender specific costumes?

Just got Ren Faire as a present for the holiday (and for being an awesome human being) and am loving it.

However, based on a few cards, it seems that certain costumes are only playable to specific genders. I saw nothing in the rules about this, yet it seems to be the intention. Is that correct? And if so, which costumes in particular are gender specific? Currently we have been playing that the lady and wench can only be played to the females, with the lord only playable to the males.

Nope, cross-dressing is fine. That's part of the fun!
