In Western weddings, the bride’s father traditionally walks her down the aisle to the altar where vows are exchanged. This is a tradition harking back to the days of arranged marriages where the bride would be given to the groom in exchange for a dowry. Nowadays, it’s a symbol of endearment to the Dad and he escorts her down the aisle.
These days that’s very different! Not least because there’s not always a bride…or maybe there are 2!
But back to the tradition, if the father isn’t available or didn’t fill that role, then mothers, brothers, children, or even grandparents are popular choices to stand in. Or maybe walk down the aisle together.
