As Meghan Markle begins her new chapter as the Duchess of Sussex, her Suits family couldn’t have been happier to witness her wedding day.

Suits creator Aaron Korsh shared a heartfelt note on social media after the royal wedding, where he reflected on his experience watching the former star marry Prince Harry at Windsor Castle’s St. George’s Chapel on Saturday. Meghan’s former cast members, including her TV husband, Patrick J. Adams, Gabriel Macht, Gina Torres, Sarah Rafferty, Rick Hoffman and Abigail Spencerall attended the ceremony.

“I can tell you the wedding was the most extraordinary thing I’ve ever seen,” Korsh recalled. “From the second we left our castle-esque hotel to the drive up to and through Windsor, to the walk to the Chapel and then afterwards to the reception, it was one once in a lifetime experience after another.”

The 51-year-old writer and producer went on to describe Harry as “looking earnest and somehow vulnerable,” and Meghan “looking strong and proud and regal and beautiful” as she walked down the aisle in her timeless Givenchy wedding gown.

“Just being in the chapel to experience such a seemingly world-changing event was incredible,” he marveled. “To have the mix of cultures on so many levels and to have two such capable ambassadors showing the world how it should be was moving beyond words.”

Korsh continued to set the scene at the afternoon reception held at Windsor Castle, where he was overwhelmed by the fact that he was “momentarily in step with Sir Elton John and George Clooney,” and was mesmerized by the Hollywood A-listers, like Idris Elba, milling about. “From there it was again one once in a lifetime encounter after another,” Korsh wrote. “All this while sharing it all with my wife and members of the Suits family.”

“I can only sum it up by saying it felt like the world was becoming a better place today,” he ended his note. “But one thing is for sure, my world will forever be richer for having those memories stored away in my consciousness.”
