Michael Kors has an enduring love affair with the ’70s.

It’s so strong that the American designer time-traveled to Studio 54 Thursday morning when he unveiled his fall collection at Cipriani Downtown under a set of giant, spinning disco balls.

His front-row glitterati was equally fab: Kate Hudson, Olivia Wilde, Priyanka Chopra, Kerry Washington, Regina King, Catherine Zeta-Jones and Michael Douglas. The VIP list goes on (and on).

Models smiled as they slinked around the curved runway in looks that screamed the last days of disco: Gold lame frocks! Feather boas! Jumpsuits! More than one outfit boasted a piece emblazoned with the “Studio 54” logo on it (in sparkles, of course).

The event closed when ’70s supermodel Patti Hansen, 62, stormed the runway in a shimmery gold pantsuit and joined surprise guest performer Barry Manilow on stage. For his part — and to the delight of the audience — Manilow performed his hit “Copacabana” dressed in a bold orange jacket dripping with crystals. Groovy baby.
