In her previous life as an actress, Meghan Markle might have gotten used to walking down red carpets, but now that she's changed her career to being a duchess, there haven't been quite as many of those events in her daily diary—although there's still plenty of glamour built into the royal schedule, of course. But on Sunday, July 14, Markle attended the London premiere of The Lion King with her husband, Prince Harry, on her arm, marking her first red-carpet appearance with him and as a royal. An iconic moment to be sure—made even more so by a subsequent hug with Beyoncé—but what really caught our eye? The chic LBD she was wearing.
