Known professionally as Biki, Bouyere was a notable Italian fashion designer and couturier of the post-war period based in Milan.  The granddaughter of composer Giacomo Puccini, her clients were mainly connected to the La Scala opera, and she is chiefly known as the creator of the style for Maria Callas, whom she first met in 1951 at a dinner party organized by Wally Toscanini.  Among many other pieces, Biki designed a plain black evening cape in wool crepe for Callas that she wore for the 1970 opening of the Teatro alla Scala season in Milan and the floor-length dress with silk satin collar which she wore in 1973 for the farewell concert at the Royal Festival Hall in London.
