This is an old tradition that doesn't really sit well with some people nowadays. Women do not "belong" to anyone but themselves, thank you very much. However, having someone walk you down the aisle can be a lovely thing. It could be one parent, both of them, or another special family member or friend. They could walk you halfway, if you want (if it's good enough for Meghan Markle, it's good enough for us). You can also choose walk yourself down the aisle. It is absolutely and completely up to you.
