• Meghan Markle wore a blue dress and matching necklace on "The Late Late Show with James Corden."
• The duchess wore Velvet Torch's $30 puff-sleeve dress during a video chat with Corden.
• The item was sold out on Nordstrom Rack's and Velvet Torch's websites at the time of writing.

The Duchess of Sussex stunned in a blue dress and matching pendant for a quick video chat on Thursday's episode of "The Late Late Show with James Corden."

Meghan Markle appeared briefly during James Corden's segment with Prince Harry after the TV host insisted that they call the duchess outside "The Fresh Prince of Bel-Air" house. Corden took Harry to the home as part of a tour of Los Angeles and even got the royal to rap the words to the '90s sitcom's theme song while they were there.

"Give me your phone. How do I find the duchess?" Corden asked Harry before using his phone to call Markle.

"I think this is where you should live," Corden told the duchess when she answered the phone. "You would be the fresh princess of Bel-Air."

Markle appeared on the screen in a $30 puff-sleeve dress from Velvet Torch. The Los Angeles boutique confirmed the duchess was wearing its smocked dress in an Instagram post shared on Friday.

"So this happened today!!" the brand wrote on Instagram.

At the time of writing, the puff-sleeve smocked dress from Velvet Torch was sold out in blue on Nordstrom Rack's and the brand's websites. But a representative for Velvet Torch told Insider it was accepting preorders and that the dress would ship no later than March 15. A similar style in black from the same brand is also available from Nordstrom Rack in sizes extra-small to extra-large.

Markle completed her look with a matching blue necklace and natural makeup.

The duchess also revealed her nickname for Harry during the video call.

"Haz, how is your tour of LA going?" Markle asked Harry.

"Haz? I didn't know we were calling you 'Haz' now," Corden said.

"You're not my wife, so - " Harry responded before calling the TV host "the worst tour guide in LA."

Corden joked that he was Harry's only tour guide - the royal said earlier in the interview it was his first time sightseeing - and therefore also the best.

During the interview, Harry also spoke about his relationship with Markle, moving away from royal life, Archie's Christmas gift from the Queen, and his thoughts on Netflix's "The Crown," among other topics.
