This week was a wardrobe win for monarchical matron Kate Middleton, in blue finery, and royal-to-be Meghan Markle, who looked prim and polished during her engagement announcement to her equally style savvy fiancé, Prince Harry. On this side of the pond, all eyes were on leading lady, Melania Trump in a snow-white Dior dress, as she traipsed the White House halls in a sea of frosted Christmas trees. While the Nutcracker Ballet performance she was surprised with during the unveiling of the White House decorations was an elegant seasonal touch, it was the FLOTUS who was the true holiday star of the show.
It's safe to say that British and American royalty shined like crown jewels this week, but Hollywood starlets like Margot Robbie and Allison Williams, who attended the 2017 IFP Gotham Independent Film Awards, also wore garments not to be missed.
