The Brit recently stepped down as Chloe's creative director after six years to take over the prime Givenchy role from Riccardo Tisci, who left the company last month (Feb17).

Keller has been replaced by Natacha Ramsay-Levi at Chloe.

"The teams join me in warmly welcoming Clare Waight Keller into the Givenchy family,” chief executive officer Philippe Fortunato said, making the new appointment announcement in a statement. "I am very excited to see Clare bring her singular sense of elegance and modernity to Givenchy... I am convinced Clare will help Givenchy reach its full potential.”

Keller becomes the first woman to head up the famous brand. Tisci held the job for 12 years; the longest tenure since founder Hubert de Givenchy was in charge.

"Hubert de Givenchy’s confident style has always been an inspiration, and I am very grateful for the opportunity to be a part of this legendary house’s history,” Waight Keller said. “I look forward to working with the teams and writing a new chapter in this beautiful story.”

Waight Keller will unveil her first collection for the label during Paris Fashion Week in October (17).
