Secondhand Shopper Alicia Silverstone

Alicia Silverstone shops secondhand to save people' lives.

The actress - who is a dedicated vegan - follows an eco-friendly lifestyle but says it doesn't mean her style is sacrificed.

She said: "My second stop would be organic cotton. Then you get it really locally, and it already exists. I know if you're not happy with what you have, you want to change it out more. Shoes are a little trickier, but they exist. I'm trying to save the planet. I'm trying to save our lives."

The mother-of-one also says it's important to use cosmetics that haven't been tested on animals even though they're not always easy to come by.

She said: "It took so much effort to find out what products aren't tested on animals - that was an ordeal. But then when I became into eco, it took out all of that: if you're using all-natural products that have no toxic chemicals, it narrows the playing field."
