When you are in the wedding party, you usually dont have any control over who you walk the aisle with and probably dont know them until someone says "This is who you are walking out with" at the rehearsal. Its only dictated by where each of you are lined up as groomsmen and bridesmaids. I was third as a groomsman out of like 7 or 8. His brother (best man), his best friend, then me, then others. On the brides side, it was the maid of honor (her sister), then her other sister, then her best friend and others after. I came out with her best friend. She was white. My boy is Armenian and his wife is Cuban/White.
