The Monaco royal tots along with the other young bridal party members all wore custom outfits by Marie-Chantal, a rep for the designer confirmed to HOLA! USA. “Princess Marie-Chantal designs exclusive outfits occasionally for her friend's weddings,” the rep noted. The last time the Greek royal designed pieces for a wedding was back in 2015 for heiress Nicky Hilton’s nuptials. While the luxury childrenswear line does not currently offer bridal clothes online, they do have a number of items perfect for weddings including the label's "Princess" dress and suits for boys.
