"Karl Lagerfeld muse Pharrell fully embraced the Chanel designer's look - from the custom-made tails right down to the diamond brooch detail and layers of black pearls. Taken from the 2009 spring archives, the look had just the right amount of dandy for the occasion."

. The designer shared the moment with a heartfelt message on Instagram, writing, "To me, every woman is a star and every star has a story.

"The best celebrity fashion is always about more than just The Dress. As this year's fashion crush, there was a lot of focus on what Ruth Negga would wear to the Oscars - and her beautiful red lace Valentino gown didn't disappoint. But what I loved most was that she used her platform for something meaningful; adorning it with a blue ribbon in support of the American Civil Liberties Union. The actress' character Mildred in the film Loving based on a true story about an interracial marriage in the late 60s - was represented by the ACLU."
