The Duchess of Sussex appeared at Paris Fashion Week to support a fashion designer friend on Saturday.
Meghan attended the Balenciaga show after making the solo trip across the Atlantic.
She has worn a number of designs by the fashion house's new creative director Pierpaolo Piccioli and the visit reflected "her support for his new creative chapter", a spokesman for the duchess said.
It was her first time at the fashion spectacle for more than a decade.
Meghan, 44, was pictured greeting Vogue's global editorial director Anna Wintour and film director Baz Luhrmann at the star-studded event.
The duchess, who announced her arrival in Paris with an Instagram story, wore a white outfit of wide-leg trousers and a matching blazer from the collection for the show on Saturday.
She completed the look with black pointed-toe heels and a slicked-back bun.
She was later pictured in a sleek black dress.
The spokesman said: "Over the years, the duchess has worn a number of designs by Pierpaolo.
"They have worked closely together collaborating on design for key moments on the world stage.
"She has long admired his craftsmanship and modern elegance, and tonight was no different.
"This evening reflects the culmination of many years of artistry and friendship, reflected in her support for his new creative chapter at Balenciaga."
Meghan's Instagram video also showed her making her way to the event in a car driving through the streets of Paris.
Paris Fashion Week runs until Tuesday, featuring big-name brands including Louis Vuitton, Dior, Chanel and Hermes.
Meghan, a former actress on TV drama Suits, recently starred in a Netflix series in which she described her 'high-low' style approach to mixing designer and accessible fashion.
Earlier this year, she also launched a new digital shop, allowing fans to purchase her favourite clothing, accessories and jewellery recommendations.
The Duke and Duchess of Sussex currently live in Montecito, California, with their two children Archie and Lilibet.
The duchess is last known to have visited the UK in September 2022 to attend a charity event and she was in the country when Queen Elizabeth II died. She and Prince Harry then stayed on for the funeral.
Earlier this year, Prince Harry lost a legal challenge over the levels of security he and his family are entitled to while in the UK.
The duke had been seeking to overturn a decision that had downgraded his security after he stopped being a working royal and moved to the US.
Prince Harry has made several trips to the UK in recent years for a variety of engagements including for charity events and to attend court cases.
Last month, he met his father King Charles amid speculation about a reconciliation.
This week Prince Harry appeared to dial in for a High Court hearing in a case against the Daily Mail's publisher.
