My understanding is that Leviticus 13 1-46 discusses leprosy specifically while 47-59 is for molds in general.
Taken somewhat out of context, but that aside -
Your question seems to suggest that you believe it's okay to wear moldy clothing to non-Jewish religious ceremonies. Whereas I would think this to be something of a faux pas across most religious lines.
("Chuck, I'd be honored to serve as your best man. And since you're getting married at the Cathedral of Mary Our Queen, and not at Temple Beth Shalom, I think I'll wear my charcoal suit with the visible green mold.")
While I agree with your sentiment, I simply find it interesting that regulations for mold were explicitly discussed in the Bible whereas today it is simply assumed that moldy clothing should not be worn.
