Indeed, regardless of where the groom is from, on that day, the groom adorns himself in the bride's culture, and things are done in the way of the bride's culture.

In my culture, it's almost the same thing except for the sitting down on the lap, the bride's hand is placed on the groom and his family's hands, and an admonishment is given to them to take care of their daughter, or return her the same way she is given if they are tired of her but not maltreat her.

Beautiful picture you've got here and wish you more happy married life.
