This Monday, fashion spectators from all over the world flooded Grand Central Terminal for Zac Posen's Fall/Winter 2015 showing at New York Fashion Week. Rihanna, Katie Holmes, and Mary J. Blige were sitting front row, and watched as stunning garments hit the runway with beautifully sleek hair and makeup to match.

The key makeup artist for Zac Posen's show is Kabuki, a living legend and the mastermind behind fashion shows for Jeremy Scott, The Blonds, August Getty, and more. And designers aren't the only ones on Kabuki's roster — he's also worked with megastars like Michael Jackson and Kylie Minogue. More recently, Kabuki is responsible for the makeup behind Katy Perry's "E.T." music video, as well as Rihanna's "Where Have You Been."

When prepping for fashion week shows, Kabuki says that most designers schedule a test day so he can look at the collection and collaborate with them on the makeup look. "Zac's show is a moment for glamour," he tells us. "He tends to show me his mood board for his collection and has a scrapbook of what he is thinking." Check out the photo gallery for a backstage pass to the Zac Posen show and to see the looks Kabuki came up with.
