Kensington Palace announced Wednesday that Prince Louis, the third child of the Duke and Duchess of Cambridge, will be christened on July 9.
Louis will be wearing the same cream lace and satin gown worn by George and Charlotte.
Christenings are a must for royal babies. Understandably, the gown had some wear and tear, so babies since then have used a replica commissioned by Queen Elizabeth, pictured below on Princess Charlotte.

In keeping with royal tradition, Prince Louis will be baptized at the age of three months old. William and Catherine have picked mainly friends rather than royal relatives as godparents to their older two children, George, 4, and Charlotte, 3.
Royal fans are set to get their first glimpse of the newest member of the Cambridge clan, with the announcement of Prince Louis's Christening.
