Since they arrived in London last week to wrap up their duties as senior royals, Meghan Markle and Prince Harry have delivered a masterclass in classic dressing. The Duke and Duchess of Sussex do everything with style, and their final event was no exception. At today’s Commonwealth Day celebrations, the pair arrived at Westminster Abbey looking like they’d just stepped out of a fashion editorial—much to the delight of the crowds waiting outside. His tailored blue suit with turquoise tie perfectly complimented her emerald Emilia Wickstead dress with built-in cape, another example of the couple’s habit of subtly matching. (Look closely, and you’ll see the lining of Harry’s jacket is the same vivid emerald at Meghan’s outfit.)

Throughout her time in the royal spotlight, Markle has used her wardrobe to champion British fashion talent, female creatives, and designers of color. Her departure from the house of Windsor should allow her greater freedom of expression—in and out of the fashion sphere—but it leaves a hole within the staid world of royal dressing. Still, the Duchess went out with a bang, bringing life to the proceedings with a vibrant style moment.
