Princess Madeleine at Prince Alexander's christening

Sarah found that Princess Madeleine wore an Erdem creation to Prince Alexander's christening on September 9, 2016. It features a white collar and blue themed floral design. She wore her hair up with a black bow and black heels.

Prince Alexander was christened in the Royal Chapel at Drottningholm Palace. His godparents were his paternal aunt, Crown Princess Victoria; maternal aunt, Lina Frejd; paternal cousin (nephew of King Carl XVI Gustaf), Victor Magnuson; Carl Philip's friend, Jan-Ake Hansson; and Sofia's friend, Cajsa Larsson.

Archbishop Antje Jackelen performed the ceremony, and "Twinkle, Twinkle, Little Star" was played. The little prince's grandfather, King Carl XVI Gustaf presented his youngest grandson with his Order of the Seraphim baby sash. He shook Alexander's hand, and, adorably, the little prince refused to let go of his grandfather's hand!

He wore the same christening gown as his older cousins, which was first worn by Prince Gustaf Adolph in 1906. 

Prince Alexander, Duke of Sodermanland is fifth-in-line to the Swedish throne.
