Usually, the bride can choose to be brought in by her mother, sister, sister-in-law or close friend. These women can accompany the bride across the red carpet and show the bride's beauty and elegance to the groom's family and friends at the ceremony.
Of course, it depends on the specific cultural traditions and the provisions of the wedding ceremony. In some cultures and traditions, the bride must be brought by her father, but if her father has died, she can choose other ways to enter the wedding scene, such as being brought by her brother or cousin.
In short, the bride can choose her favorite way to enter the wedding scene and make a decision according to the specific situation.
