The words “icon” and “legend” are thrown around a lot these days, but Norma Kamali has truly had a fabulous career. Her use of unusual materials like sweatpant fabric, stretchy cotton Lycra, and even sleeping bags revolutionized womenswear. And that’s just the beginning.

Kamali created costumes for The Wiz, and outfitted Chaka Khan and Sly and the Family Stone. And as she tells Nicole Phelps and Vogue’s senior archive editor Laird Borrelli-Persson, in its early days, her New York City store was the place to see, be seen, and get dressed—hosting the likes of Mick Jagger, Keith Richards, and the New York Dolls’ David Johansen, who would pop in and “just literally change in the store, then leave what they had on for us to throw away.”

On this week’s episode of The Run-Through, Kamali shares her wide-ranging thoughts on everything from the stylishness of the ’70s, the flattening effect of social media on personal expression and creativity, why she wants her staff to use AI at work, and the reason she opted not to celebrate her 80th birthday. “It’s a milestone, but if I celebrate it, it makes it bigger than I am envisioning 80 to be,” she says. “My endgame is 121, so celebrating 80 is maybe a little too premature—the dance party will have to wait ’til 100.”
