Kate Middleton might be dressing for her role as future Queen, but that doesn't make her immune to the season's hottest trends. For a Buckingham Palace garden party on May 20, she dug into her closet for an old Emilia Wickstead dress that leans into this spring's butter yellow phenomenon. And on May 22, the Princess of Wales made a surprise appearance in Scotland with Prince William while tackling the nautical trend—and channeling Princess Diana in the process.
The Princess of Wales, who serves as sponsor of the new Royal Navy warship HMS Glasgow, attended the ship's naming ceremony with Prince William, smashing a bottle of local Scottish whisky against its hull. Her navy and white Suzannah coat dress—crafted from Italian wool crepe—brings to mind the sleek styles favored by Princess Diana in the '90s and per the designer, "was inspired by vintage couture fashion."
