She has always had a slight frame, perfect for fitting into haute couture pieces by Chanel and Alexander McQueen. Now Daphne Guinness has revealed the secret to her tiny sample-size body.
A new interview has revealed how she announced: 'I'll eat when I'm dead,' when offered lunch during a photo shoot.
Revealing that the 43-year-old had been existing on Red Bull and Ensure nutrition shakes for most of the day, the New Yorker told how she refused her assistant's offer of a plate of pasta.
She explained: 'If I eat, I can’t work.'The magazine also revealed that her couture wardrobe comprises 2,500 garments in total, as well as 450 pairs of shoes, 70 hats, and 200 handbags.
The vast collection is stored at her homes in London and New York, but around 100 of her most important pieces are currently on display at the Museum at FIT in New York.
Given the show, it is one of a number of interviews that the artist and heiress has given in recent weeks.
Another, with the Daily Beast, proved equally provocative when she lamented the lack of risk-taking in fashion these days.
Blaming the fact that stars often wear a garment because they have been paid by the label, and are dressed by stylists rather than putting their own stamp on a look, she said there was a 'blandness that’s spread across the world.'
She explained: 'People stopped dressing themselves, they let other people do it for them, or they get paid to wear things down a red carpet.'
She added that music, which has always influenced fashion, appears to have less social and political ambitions these days, so has less creative influence on the fashion scene.
'There used to be movements and then that sort of died after the New Romantics and grunge,' she said.
Indeed, with her penchant for towering platform heels, two-tone hair and haute couture, Guinness could never be accused of being boring.
She was abhorrent when asked if she had ever been paid to wear any designer's work.
'No f****** way. That would be terrible,' she told the site. 'Then it wouldn’t be real, and everything I’m telling you now would be a complete lie. I wear it if it's [designed by] a friend.'
And we would all undoubtedly be doing the same if, like Guinness, our friends counted Philip Treacy and Karl Lagerfeld.
She was also a huge champion of the late Alexander McQueen and close with Isabella Blow, who committed suicide in 2007.
'A lot of my friends died, and we were a gang,' she said of them. 'I’ve become more visible since they disappeared. I’ve been more exposed.'
On her own style Guinness's statements were equally intriguing. She called her approach to fashion 'unconscious' and her hair 'a series of dire mistakes'.
And as for Lady Gaga, whose look often echoes that of the heiress, she sees neither insult or compliment.
'Human beings all mimic each other,' she said. 'I'm probably mimicking someone else, too.'
