Sarah found that Queen Silvia of Sweden wore a baby blue Valentino dress to the christening of Princess Leonore of Sweden, Duchess of Gotland. 

Princess Leonore, the elder child and only daughter of Princess Madeleine of Sweden and Christopher O'Neill, was christened on June 8, 2014. This also happened to be the 1st wedding anniversary of her parents. 

She was baptised in the Royal Chapel of Drottningholm Palace with Anders Wejrd, the Archbishop of Sweden. Her godparents were Crown Princess Victoria, maternal aunt; Tatjana d'Abo, paternal aunt; Patrick Sommerlath, mother's maternal cousin; Count Ernst Abensperg und Traun, paternal uncle by marriage; Alice Bamford, friend of her parents; and Louise Gottlieb, friend of her parents. 

She wore the traditional christening gown for the family, which was first worn by Prince Gustaf Adolph (later King Gustaf VI Adolph) in 1906. 

Leonore was born on February 20, 2014, in New York City. By birth, she is an American citizen, as well as a Swedish citizen.
