In Korea, there were some traditional traits. Actually, I don't know well but I remember one thing. When my parent got married, my father had to be slapped his the sole to his friends. This mean is celebrating for their marriage and wishing his health. Nowadays, that is not common and almost couples just do formal wedding. It means they usually do a ceremony and a wedding and a reception that it! The time is just about one hour and half. This is not special. If I get married with someone, I will do the wedding as a small and simple wedding because this is not important doing that. It's more important later get married!
