One day, two strikingly chic outfits for Meghan Markle. After meeting with Australia's prime minister, Malcom Turnball, and his wife, Lucy, to discuss the upcoming Invictus Games in Sydney this afternoon, the soon-to-be royal seamlessly switched from day to night without missing a beat.

Earlier in the day, Markle wore a pleated floral dress by Self-Portrait—an appropriate daytime option—with classic Jimmy Choo pumps and an Alexander McQueen jacket she recycled from a previous event in February. A couple of hours later, the 36-year-old went with a more tailored option to celebrate Queen Elizabeth's 92nd birthday at Royal Albert Hall.

Markle's concert-ready getup consisted of a fitted navy cape dress by Stella McCartney and blue suede Manolo Blahnik heels. A boxy clutch with a sleek gold handle complemented her structured look.

Prince Harry got the all-blue memo, and suited up in tailored slacks and a jacket, unavoidably twinning with his lady. Meanwhile, a crisp white dress shirt provided a clean backdrop to his matching navy tie.

At the Queen's birthday concert, Meghan and Harry will enjoy performances by London's top talent, including Kylie Minogue, Sting, and Sir Tom Jones. Fingers crossed for super cute snaps of the couple showing off their dance moves!
