What's an elegant way to label the person walking the bride down the aisle in the program, if not her father?

My brother will be walking me down the aisle in place of my father, who is deceased. How should my brother's name be "labeled" in the program where the wedding party members are listed? With "Father of the Bride," it's usually implied that the person walking the bride down the aisle is her father, but not so much with "Brother of the Bride."
