I was wondering if this was part of their culture, then I started wondering why havent we seen any ghoul culture up to this point. In tokyo ghoul it seemed that it was a every man for himself type mentality so where did this ghoul culture and comradery come from?

Ghouls have specific outfit they marry in? Now that's something interesting. Some part of me hopes that Ishida will elaborate on ghoul culture and or customs, with all this wedding stuff coming up. This is only speculation though, as the outfits seem way too stylized to be something random Tsukiyama threw together.
