"I've always found Diane's effortless sense of style so inspirational," Jason told InStyle recently. "To me, the bag is refined, feminine and timeless, words that I would also use to define Diane."

Her impeccable taste gibes well with label's sophisticated collections. The fashion world adores Diane, too, because she likes to have fun, take risks and get noticed — all while looking incredibly chic in clothes.

"I met her as the girlfriend of a good friend," Tisci has said of Kim, referencing Kanye. "I just wanted a moment with her to understand — and I fell in love. She's the Monroe of our age. People think she's like a doll, but actually she's tough and clever." Photo: © Getty Images 4/18 Audrey Hepburn & Hubert De Givenchy Audrey Hepburn was the original Givenchy muse. Here is the late icon, circa, 1991 alongside designer Hubert De Givenchy in New York City. He created her trend-setting looks for "Breakfast at Tiffany's," and their friendship would span decades after. "His are the only clothes in which I am myself," she said. "He is far more than a couturier, he is a creator of personality."

"It's been an amazing collaborative experience; a casting that’s turned into a friendship,” Posen, who designed her wedding dress, recently told Lucky Magazine, with Coco chiming in: "I always say this, but you’re like the perfect older brother in the industry — especially because you grew up in it."

The pair met as neighbors in the same New York City apartment building and Erin became a stylist for Wang's once-nascent, now-multinational eponymous fashion label. The duo are known for their post-grunge, sporty downtown style.

Charlize, a spokes-celebrity for the brand's J'Adore fragrance, has earned the enviable perks of getting to wear Dior gowns on the red carpet. Photo: © Getty Images 9/18 Tilda Swinton & Haider Ackermann Tilda Swinton and her close friend, designer Haider Ackermann, turned heads at Tokyo's Fashion Week in October 2014. The actress, revered for her fashion-forward, androgynous style, told Vogue in a recent interview, "There are very few clothes that really move properly, in relation to the body, like Haider's do — that feeling of them being designed for movement; designed for the body; for the gesture. I really love the way in which he designs for a moving human body and you'd think in fashion that's not such a tall order but it is." Photo: © Getty Images 10/18 Gwyneth Paltrow & Stella McCartney Stella McCartney and Gwyneth Paltrow have been friends for a long time, and their sartorial aesthetics match up: They're both eco-conscious, streamlined and prefer understated rather than over-the-top glamour. Photo: © Getty Images 11/18 Natalie Portman & Kate and Laura Mulleavy Natalie Portman is tight with Kate and Laura Mulleavy, the sisters behind the cool-girl label Rodarte, and she has worn their ethereal gowns to the Oscars as well as her 2012 wedding to dancer-choreographer Benjamin Millepied.

Photo: © Getty Images 13/18 Blake Lively & Christian Louboutin Blake Lively lives a charmed life indeed. The Gossip Girl bombshell and red-soled shoe guru Christian Louboutin are very friendly, and he even named a strappy sandal after her in 2011. "He said: 'Do you love it?' I said: 'I want to sleep with it under my pillow every night' and he said: 'We're naming it the Blake then,'" she said at the time. "It was insane. It's like my greatest accomplishment." Photo: © Getty Images 14/18 Blake Lively & Karl Lagerfeld Blake is also a popular muse for none other than man-myth-legend Karl Lagerfeld, who helms Chanel. Karl, who loves a pretty face, has called the actress "a kind of American dream girl."

Nicola was formerly artistic director at the French brand Mugler.

Then an ingenue, Sienna Miller set trends in breezy, colorful styles by longtime friend Matthew Williamson, a designer also known for having fun with fashion and not taking it all too seriously. It's only fitting that Sienna was — and still is — his no. 1 muse.

He likes her so made her the face of his namesake perfume. Marc once described Sofia as "Young and sweet and innocent and beautiful. The epitome of this girl I fantasize of."
