King Charles is truly a reigning expert on royal duties and his wife's go-to heels, too. During a meeting with the founder of British footwear brand Sole Bliss, the monarch, 76, charmed entrepreneur Lisa Kay by showing just how well he knows his queen - not just in matters of state, but in style as well. "The King was relaxed and personable," Kay, who has been supplying shoes to Queen Camilla since 2018, told People on Friday, September 19, revealing Charles impressed her with his knowledge about what type of heel that Camilla, 78, favors.
