Animal rights organisation PETA has unveiled its new I'd Rather Go Naked Than Wear Wool campaign starring Hollywood actress Alicia Silverstone.

The Clueless actress was shot by renowned celebrity photographer Brian Bowen Smith, and commented 'It's just so fast, the shearing process. (The sheep are) cut, they're harmed. They get very seriously wounded, and there's no care for them when they're wounded. It's just, "Move on to the next"'. Silverstone is promoting a #WoolFreeWinter, and other PETA campaigners include Eva Mendes, Olivia Munn, Elisabetta Canalis, and Penélope Cruz.
