Iris Apfel, a New York society matron and interior designer who invaded the fashion world with a brash bohemian style that mixed hippie vintage and haute Couture, died on March 1 at her home in Palm Beach, FL. She was 102.

Calling herself a “geriatric starlet,” Ms. Apfel in her 80s and 90s set trends with irreverent ensembles: a boxy, multicolored Bill Blass jacket with tinted Hopi dancing skirt and hairy goatskin boots; a fluffy evening coat of red and green rooster feathers with suede pants slashed to the knees; a rose angora sweater set and a 19th-century Chinese brocade panel skirt.

“When you don’t dress like everybody else, you don’t have to think like everybody else,” Ms. Apfel told Ruth La Ferla of The New York Times in 2011.

For decades starting in the 1950s, Ms. Apfel designed interiors for private clients like Greta Garbo and Estée Lauder. In 1992, she and her husband sold their company, and she became a soaring free spirit known in society and to the fashion cognoscenti for ignoring the dictates of the runway in favor of her own artfully clashing styles.
