Stella McCartney was born in 1972, the daughter of pop star Sir Paul McCartney. She is the youngest of three sisters. One sister is a potter and the other sister does the same job as their mother used to do - she works as a photographer. Stella's brother, James, is a musician. Stella first hit the newspaper headlines in 1995 when she graduated in fashion design from art college. At her final show, her clothes were modeled by her friends, Naomi Campbell and Kate Moss, both well-known models. Unsurprisingly, the student show became front-page news around the world. Stella hadn't been in the news before as a fashion designer but she had spent time working in the fashion world since she was fifteen. In March 1997, Stella went to work for the fashion house Chloe. People said the famous fashion house had given her the job because of her surname and her famous parents but Stella soon showed how good she was. She designs clothes which she would like to wear herself, although she's not a model, and many famous models and actors choose to wear them. In 2001 Stella started her own fashion house and has since opened stores around the world and won many prizes. A lifelong vegetarian, McCartney does not use any leather or fur in her design. Instead, she uses silk, wool and other animal-derived fabrics.
