She's a devoted activist when it comes to causes she's passionate about.

And Pamela Anderson is now taking on climate change as an executive producer of new documentary This Changes Everything.

The actress, 48, wore a surprisingly shapeless white dress that called to mind a raincoat and thoroughly covered her famous curves as she attended the film's premier at the Toronto Film Festival on Sunday.

Anderson's off-white dress featured four front-pocket details and a wide waist.

It had a black zip up the front, which Anderson left partially unzipped, giving a glimpse of her white top underneath.

The blonde beauty rolled the long sleeves up to her elbows for a casual, lived-in look.
