Sienna Miller Is Wearing the Newest Chanel Lip Product — and You're Going to Be Obsessed

As a bride-to-be, my first thought when I saw Sienna Miller's soft and romantic makeup at the 2017 Golden Globes was, "I want to wear that down the aisle." Her makeup artist, Kate Lee, who has been working with Sienna since the '90s and exclusively used Chanel products, flawlessly played up Sienna's features with lush lashes, clean eyeliner, and a medley of rosy nudes.

When we chatted exclusively with Lee via email after the red carpet, we learned two key things about Sienna's look. The first is that Lee was inspired by 1960s Hollywood beauty to craft the soft palette and timeless style.

Lee said: "Sienna's Look for the Golden Globes 2017 was inspired by Brigitte Bardot and Jean Seberg and that very specific brand of beauty that was born of the 1960s. Beautiful, classic, but effortless. We took what we wanted from the references, and then made it our own. It was a collaborative process which included Sienna, myself, and Earl Simms, who is her long time hairdresser."

FYI, Sienna wore an elegant black ribbon tied around her ponytail, a nod to accessories seen on both Bardot and Seberg.

The second key piece of information we discovered is that Sienna is one of the first celebrities to rock Chanel's new Crayon de Couleur Jumbo Longwear Lip Crayon (available in 11 shades for $37 each). As early testers of the lip crayon, we can confirm its creamy formula. The finish is more of a glossy matte than a dry one.

To choose Sienna's hue for the evening, Lee swatched out the shades (and you can see an exclusive photo ahead). "When I receive a new range of lip color, I like to test it first as it gives me an idea of how much pigment and emollience is in the product," Lee told us. "By understanding the texture and pigment, I find it helps me to figure out how to achieve different looks by blotting, layering etc."

She selected No.1 Nude option to go with Sienna's '60s style. "Because we were pretty much set on our references, I knew that I would use a nude blush shade, and it just happened to be perfect," Lee explained. "I had a few other matte shades on hand but because Sienna was quite tanned, I felt that a moist lip would look more modern."

Though lip crayons are generally pretty easy to use, we wanted to get Lee's advice on how to apply this buzzy launch. "Lip Crayons are the best of the bunch when it comes to ease-of-use and portability," she noted. "They impart great color and moisture, which you can then blot and layer or use over contrasting or corresponding shades to build depth and intensity. My favorite way to use them is to apply from the pencil and then gently dab with my ring finger to work the color into the lip and soften the lip line."

And of course we had to know what it's like to get ready with Sienna! Lee said, "Sienna and I have worked together for over 15 years, and it's always such fun and so inspiring for me to work with her. She is truly a beautiful person, inside and out. Today we listened to David Bowie in honor of his birthday and there was a champagne toast just before she left!"
