Met Gala: Princess Beatrice added a touch of royal glamour as she arrived in sweeping lilac gown

British Princess Beatrice made her Met Gala debut in a vivid purple gown fit for a princess.

The 29-year-old, who is Queen Elizabeth's granddaughter, looked regal in her gown with its long sleeves, cinched waist, and high neckline. She completed her ensemble with a black clutch and a shiny headpiece.
