Various designers and editors from the U.K.'s Harper's Bazaar magazine have recognised the top 20 most stylish celebrities in the country and Moss, Harry Potter star Watson, Pirates of the Caribbean beauty Knightley, and singer Florence Welch have all made the cut.

British royal, Catherine, the Duchess of Cambridge was also selected for her modern elegance alongside Stella McCartney, who recently hit the headlines for designing the wedding gown worn by her dad's new wife, Nancy Shevell.

Actresses Tilda Swinton, Thandie Newton and Kristin Scott Thomas were also included, as was Colin Firth's Italian film producer wife Livia.
