E! has set up a photo gallery to introduce you to all members of the royal wedding party, so you’ll know who you’re looking at when the big even takes place on April 29.

You’ll definitely recognize Best Man Prince Harry, 26, the second son born to Charles and Diana, the Prince and Princess of Wales. Pippa (Philippa) Middleton, 27, Kate’s younger sister, will serve as Maid of Honor.

Other bridal party members include Lady Louise Windsor, 7, who will serve as a Bridesmaid. She is Prince William’s first cousin, the daughter of Prince Edward (brother to Prince Charles, the next King of England), and the ninth person in line to the throne of England. Eliza Lopes, 3, granddaughter to Camilla Parker Bowles (Duchess of Cornwall and second wife of Prince Charles) will also serve as a Bridesmaid.
