Meghan Markle and Duchess Kate don blue outfits for first public engagement together

Royals in blue!

Prince Harry, Meghan Markle, Duchess Kate and Prince William made their first-ever joint appearance on Wednesday at the inaugural Royal Foundation Forum. Of course, all eyes were on Meghan and Kate, with many wondering what they'd wear for the big occasion. The two didn't disappoint, opting for ensembles that stayed true to their personal style aesthetics.

Meghan dazzled in a Jason Wu, a favorite brand of former FLOTUS Michelle Obama, navy blue sleeveless belted dress. The ensemble from the Canadian fashion designer is a subtle nod to the former "Suits" actress' Toronto roots. In fact, the star has effortlessly mixed Canadian, British and American fashion labels during her public appearances ever since announcing her engagement to Prince Harry.

The bride-to-be completed her look with a sleek pair of Aquazzura's Casablanca pumps in a black hue.

Duchess Kate took a more frugal approach with her look for Wednesday's event, donning a Seraphine frock she's worn before that displayed her blossoming baby bump. Kate added a bit of sparkle to her look with a pair of glittering Oscar de la Renta earrings.

Meghan and Kate's ensembles weren't the only things about their outing that made headlines. During their conversation on stage, Meghan expressed her support for the #MeToo and Time's Up campaigns, while Kate shared heartfelt remarks about the importance of mental health.
