It is no surprise that Beatrice, who is always seen in Armani or Valentino, showed up to the charity event. In an interview with Glamour magazine earlier this year, the royal opened up about her go-to designers.

"For formal occasions I wear Valentino or Armani because they are kind enough to let me borrow stuff," she admitted. "I couldn't afford to buy as many dresses as I need for public functions! I like to be elegant, but even then I need to be comfortable."
