Nonoo has been a close friend of Meghan’s for several years, and it has been speculated that she helped introduce Meghan and Harry. The Bahrain-born business woman, who was raised in London, has long run in royal circles. Until 2016, she was married to Paddle8 founder Alexander Gilkes, who is one of Harry’s closest friends. Shortly after Meghan met Harry, she and Nonoo took a trip to Spain together.

Meghan turned to Misha Nonoo to design a crisp white shirt for her capsule collection on behalf of the Smart Works charity. At the launch, Nonoo told PEOPLE the project “aligned so closely with my values of empowering women and dressing women for their professional pursuits, so there was no way I’d say no to it. I was asked specially to do the white shirt because that’s our signature. It was actually a very, very easy process. The Duchess is a consummate professional. It’s been a real pleasure to work with everyone on the team.”
