Fans of royal fashion have been spoiled for choice when it comes to amazing outfits lately. First, there was Prince Harry and Meghan Markle's impactful tour of South Africa, where the Duchess of Sussex supported several local designers. Then came Prince William and Kate Middleton's memorable tour of Pakistan, which saw the couple diving into traditional Pakistani looks. Now, Markle is back in London, and of course she's brought another great outfit with her.

Photographed at the One Young World Summit Opening Ceremony at Royal Albert Hall, Markle wore Aritzia's Babaton Maxwell Dress, which is on sale for just $50 but sadly already sold out. Luckily, the brilliant royal purple color is a major trend with other brands, so we've included plenty of options below.

As for the event Markle is supporting, the organization describes its mission this way: "One Young World identifies, promotes and connects the world's most impactful young leaders to create a better world, with more responsible, more effective leadership." Sounds like a worthy cause to us. Scroll down to see what Meghan Markle wore to the summit and shop the trend.
