In her first interview as a royal, Meghan Markle is revealing some secrets about her stunning Givenchy wedding dress. The Duchess makes an appearance in a new documentary about Queen Elizabeth, "Queen of the World," where she tells all about the super sneaky way she incorporated "something blue" into her wedding look. According to E!, Meghan's "something blue" was a "piece of blue fabric sewn into her veil, taken from a dress she wore on her first date with Harry." Meghan also talks about the amazing way she surprised Prince Harry and the royal family on her wedding day. Her veil, embroidered with 53 flowers from the Commonwealth countries, was a huge success. "I knew that it would be a fun surprise as well for my now husband, who didn't know. And he was really over the moon to find out that I would make this choice for our day together, and I think the other members of the family had a similar reaction and appreciation for the fact that we understand how important this is for us, and the role that we play, and the work that we're going to continue to do in the Commonwealth countries," Markle said in the upcoming documentary.
