Heiress, artist and fashion iconoclast Daphne Guinness is used to turning heads with her colorful, outlandish clothes, but she’s now raising eyebrows with her profile in this week’s style issue of the New Yorker magazine.

Guinness is the daughter of brewing heir Jonathan Guinness and ex-wife of Greek shipping heir Spyros Niarchos, but the 43-year-old has stepped outside of her privileged confines to the world of couture fashion: part Paris Hilton, part Lady Gaga.

The New Yorker details her unusual family background – her step-grandfather was married at Nazi Joseph Goebbels’ house – and describes her $15 million apartment in Manhattan that has a 60-foot mirrored corridor and matching mirrored bathroom so she can see herself bathe. More curious is the magazine’s description of her commitment to fashion.

“Uncomfortable is the name of the game,” she quipped while wearing a giant metallic collar at a photo shoot.

Later during the shoot, Guinness, who had reportedly been consuming only Red Bull and Ensure, refused to eat pasta that was prepared for the production staff:

“If I eat, I can’t work. I’ll eat when I’m dead,” she said, invoking supermodel Kate Moss’s infamous motto: “Nothing tastes as good as skinny feels.”

Daphne Guinness’s flamboyant and excessive wardrobe is currently on display at the Museum at F.I.T. in New York City, which will run through Jan. 7, 2012.
