Russian customs and traditions dating
The entire event is played out in a comical fashion and everyone is entertained.
At first the groom comes and gives something (often money or jewelry) for the bride, and so the parents of the bride bring out a woman or man (the latter for amusement) that is not the actual bride, but is dressed up like one, covered in a veil, so the groom can't see their face.
In Australia and Europe, relationships often come out of groups of friends, which I’d assume equals #instantapproval. One of my buddies took a girl he was dating for only two weeks on a family vacation, and we’ve laughed about it ever since. But why do we generally wait so long to bring her home? The underlying reason we bring her home to meet the parents is to get their approval for possible marriage. Not only do immediate family members stay close, but distant relatives do as well.
However, in other cultures, family approval is important from the get-go.
