3. Your mother could give you away, too
In the Jewish tradition, both the mother and the father walk the bride down the aisle. In the Christian tradition, though, it’s only the father. Admittedly, walking down the aisle with your father, brother, grandfather or other male relative had been a strong tradition for a long time. There’s no need to follow tradition to a tee. Convention could be bent a bit, though, if it would help honor your mother.
You could ask your mother to join you and your father as you walk down the aisle. After all, both of your parents have to say goodbye to their little girl. However, it would be reasonable to know if your dad is ok with that. Sharing this special moment will be a great way to honor your mother at your wedding.
