I went to a wedding about eight years ago that did this. The bride was a shameless HP nerd and did the whole wedding up in various house colors. My wife was the bridesmaid who got House Slytherin. We all generally had fun with it.
But other than the pastiche, it was just another wedding. Lots of dancing, lots of food, a fair amount of booze. No bruised egos over wearing a particular house color, possibly because we were all in our late 20s and not literal children.
