The designer was presented with the insignia, bestowed by Queen Elizabeth II, in a private ceremony Wednesday at Buckingham Palace.
A company statement says Lauren is the first American designer to be recognized with an honorary knighthood. Ralph Lauren Corp. has donated to a breast cancer research center in London and plans to financially support a second center as well.
Lauren said via email he's always been inspired by the history, traditions and culture of the U.K. and considers the knighthood a "very special moment" as he celebrates 50 years in fashion.
