When it comes to big names in style, Kate Middleton is right up there at the top. She makes a statement nearly every time she leaves the house, whether she’s channeling her late mother-in-law Princess Diana in a houndstooth coat or stepping out in affordable snow boots. So when the fashion darling met Condé Nast artistic director and longtime Vogue Editor-in-Chief Anna Wintour, we couldn’t wait to see what she would wear. The two sartorial heavyweights FINALLY last night, and needless to say, it was a style MOMENT.

Hot on the heels of a rare outfit controversy when the duchess went against the all-black dress code at the BAFTA Awards in a hunter green gown, Middleton met the front row regular at a Buckingham Palace event in honor of a new fashion initiative called The Commonwealth Fashion Exchange.

According to People, the initiative brought together “designers and artisans from [all 52] Commonwealth countries… to create a one-of-a-kind sustainable outfit that was showcased at last night’s gala.

Believe it or not, the event marked the first time that the Duchess of Cambridge came face-to-face with Wintour. Needless to say, both were impeccably dressed for the occasion, with the soon-to-be mommy of three opting for a ruffle-sleeved black-and-white lace floral print dress from longtime favorite Erdem which beautifully showcased her growing baby bump. She topped the look off with classic black pumps, Anita Dongre Shameera Earrings ($1,251) and her signature bouncy brunette curls.

It seems that Middleton, 36, struck the right tone for the evening too, because Wintour, 68, also wore a bold printed dress by Erdem, and suddenly a fashionable friendship was born.

Other famous faces in attendance included British designer Stella McCartney and Sophie, Countess of Wessex, and Naomi Campbell, who was a vision in a structural green number that had our jaws on the floor.

Talk about a fashion moment!
