Alicia Silverstone strips off for PETA advert which deters people from wool

Standing barefoot in a lush green forest, blonde hair tumbling over her shoulders and a provocative pout playing on her lips, Hollywood actress Alicia Silverstone stares into the camera lens.

She’s au naturel, baring her behind in a photo for the animal welfare charity People for the Ethical Treatment of Animals (PETA), renowned for its attention-grabbing publicity. So what’s prompted the glamorous A-lister to strip off? A new campaign against wearing fur, perhaps? An attack on crocodile skin handbags or leather shoes?
