Sapna, 41, who is known for her tattoos, has appeared in the advertisement which asks people to be comfortable in their own skin and not to use fur and leather items.
Her photo in the PETA ad comes with the slogan 'Ink, not mink'.
"After I educated myself and saw a few films on the cruelty and what happens to animals, I realised that it just wasn't worth it," said Sapna.
"I take a very strong stance on leather. Pleather is a great substitute for leather. And if you don't know what it is, I just say go to your local shop and ask for that substitute because it is available."
