Natalia I didn't do any of that.
If anyone should have given me away it would have been my mother, she did all the graft bringing me up, as it happens dh and I walked in together, I wore a red dress.
However that is only one day, changing your name is a decision with lasting consequences. It's worth considering what you would do if your husband divorced you, if you remarried, if he remarried, if you had more children with your new husband.
I think it's wrong to say it doesn't mean anything anymore.
