Luxury fashion group Mulberry has unveiled a new collection of bags in collaboration with British model Cara Delevingne, hoping to improve its fortunes after a profit warning and problems overseas. The made-in-England Cara Delevingne Collection, which features three sizes in three different finishes, was launched by Mulberry in London on Sunday. She has also been the face of two recent Mulberry campaigns. Under its boss Bruno Guillon, Mulberry has increased prices to take its brand more upmarket from a traditional position of “affordable luxury” and moved to raise the company’s profile overseas, targeting affluent Asian shoppers with new stores in key tourist spots.
