Marie Kondo has been taking the world by storm with her tidying technique, but Tim Gunn is not a fan.

Gunn, 65, called Kondo’s Netflix show “very slow” and admitted he’d turned down the chance to interview the Japanese consultant for a panel at the 92nd Street Y.

The former “Project Runway” star said on “The One Way Ticket Show” podcast, “I’m not a believer. I don’t subscribe to her methods.”

He added, according to Page Six: “I have a huge number of books, as I’m sure you do. Do they all spark joy?

“Roget’s Thesaurus does not spark joy. Am I going to get rid of it? No!”
