A distinctive necklace made by craftsman Malcolm Morris for designer Alexander McQueen has been missing since a Paris catwalk show 30 years ago. Sarah Burns-Collins, who has collaborated with Morris, is seeking information about the necklace while preparing a retrospective of his work. The necklace features a taxidermy butterfly and is described as a heavy statement piece. Morris and Burns-Collins speculate it may still be in Paris, possibly in an antique shop or with a model.
