Of course, this evening is all about Prince Christian of Denmark. The ladies also clearly catch the eye at the big banquet. The motto for Denmark’s Crown Prince family is blue: Princess Mary and her daughters Isabella and Josephine show up at Christiansborg Palace with the birthday child. All the ladies choose a gown in dark blue – Mama Mary also opts for glitter in her Jesper Høvring gown, and the two teen royals opt for flowing fabric.
