From H&M's 2014 Conscious Collection, the beautiful gown has been worn by other famous royal faces. Crown Princess Victoria of Sweden and Crown Princess Mette-Marit of Norway have also sported the $215 dress. Victoria dazzled at a glam bash in her home country in the number, while Mette-Marit wore the dress to attend the amfAR gala in New York in 2014.

Victoria is such a fan of the design that she has been spotted wearing it in a different color, a nude shade, for several different occasions.

The ladies all looked lovely in the dress, each displaying their own personal style with different accessories. Mary added bright yellow pumps to complete her look, while Victoria wore block heels. Mette-Marit opted for a similar look to Victoria in blush heels.
