Misha Nonoo saw an "instant" surge of sales in her Husband shirt after it was worn by the Duchess of Sussex.
The fashion designer's close friend opted to wear one of her white oversized creations when she made her first public appearance with then-boyfriend Prince Harry at the Invictus Games in 2017 and Misha - who is rumoured to have set the couple up - admitted her business changed overnight.
Speaking to Elle for their Clothes of Our Lives series: "When a person of note—particularly someone that is so closely associated to myself or to the brand like Meghan is, and it's well documented that we have a long, enduring, and very close friendship—wears your design, there's an almost instant shift in interest and sales.
"Her platform gave a great level of awareness to our brand and our mission. I think that's just a natural phenomenon that occurs when you are fortunate enough to have a like-minded person publicise your collection, like Meghan has done with the Husband shirt.
"People buy the original in white, and then come back for more in different colours because they love it so much.
