But make no mistake: The Norwegian designer, who moved to the U.S. as a teen, is far from an overnight sensation. Though he made tons of noise for covering Beyoncé in gold onstage and later sequined red when she sat front row in the audience on Sunday, Dundas has been an all-star designer for at least a decade.
Here are five other things you should know about Mr. Dundas.
He spent time with the masters: In 1992, he was the design assistant at French haute couture house Jean Paul Gaultier. He was there for eight years.
He's held top posts before: Dundas became the artistic director of Emilio Pucci in October 2008. In 2013, he designed outfits for British singer Rita Ora’s Radioactive Tour wardrobe.
He does wedding gowns: Via Cavalli, he designed Ciara’s wedding dress when she walked down the aisle to meet hubby and Seattle Seahawks quarterback Russell Wilson in 2016.
Kim Kardashian is a fan: He became the creative director at Roberto Cavalli in March 2015. Kim Kardashian became the first person to wear a Roberto Cavalli piece created by Dundas at the 2015 Met Gala.
He's worked with Queen Bey before: Sunday wasn’t the first time he designed for Beyoncé. He was a huge part of both he solo Formation Tour wardrobe in 2015, and he provided pieces for her joint tour with husband Jay Z for On the Run.
