A wardrobe fit for a queen?

First lady Melania Trump has been turning heads with her designer ensembles during her visit to the United Kingdom and tonight’s look was the crown jewel.

Wearing a yellow shoulder-baring dress with a baby pink belt, the 55-year-old former model looked regal in Windsor where she and President Trump dined with Kate Middleton, Prince William, Queen Camilla and King Charles III.

She accessorized with large emerald and diamond earrings.

Although the first lady has not always adhered to royal protocol, this floor-length ball gown met the castle’s rigid standards.

Earlier today, the first lady stepped out in a wide-brimmed hat and gray skirt suit by Dior. She and Kate Middleton wore coordinating jewel tones that ranged from rich maroon to plum.

Not known for being verbose, Mrs. Trump often uses her attire to convey her thoughts.

She kicked off this visit, boarding Air Force One in a classic trench coat by Burberry. The British brand’s signature plaid motif peeked out of the floor-length outerwear, which was worn with Dior’s Empreinte riding boots — a black, knee-high style with a gold “CD” clasp at the ankle.

Princess of Wales chose a similar shade, stepping out in a full-length, hand-embroidered gold Chantilly lace evening coat over a silk crepe gown by British designer Phillipa Lepley.
