Groovy, baby! This ‘70s fashion staple beloved by Taylor Swift and Bella Hadid gets a retro revival

It’s a funky fad coated in 1970s swag — can you dig it? 

Foxy mamas of NYC are saying “peace out” to Y2K-inspired threads and resurrecting the vintage “Penny Lane” coat instead. 

“I just love the silhouette,” Khatia Khatiashvili, 25, a style influencer from Brooklyn, told The Post of the far-out outerwear. 

Hers is a $450 Christmas present made of Mongolian sheepskin. 

“The Penny Lane coat just elevates every outfit I wear it with,” gushed Khatiashvili. “It’s retro. It’s whimsical. It’s groovy.”

Known to most as an Afghan, the “Penny Lane” coat is a fur-embellished, figure-flaunting number, which owes its nickname to Kate Hudson‘s charismatically quirky character in the 2000 blockbuster “Almost Famous.”
