WASTE NOT, WEAR LOTS

Stella Mccartney has always been more committed than most to fashion that considers the environment (see her pioneering use of alternatives to leather), and for winter the designer has developed a new ‘regenerated’ cashmere. Her sweaters are now made with post-factory-waste cashmere, which has been mechanically recycled and spun in Italy to create a fresh batch. With 92 per cent less environmental impact, this is cashmere with conscience. Sweater, £385, stellamccartney.com.
