Rumer Willis, 25, wasn't shy about showing her support for the "Free the Nipple" fundraiser hosted by Russell Simmons and presented by Mr. Pink Beverages Thursday in West Hollywood, Calif., sporting a racy t-shirt featuring three nipples.

"Free the Nipple" is a movement which fights for women to be allowed to go topless in public.

In May, Rumer's younger sister, Scout, 22, made headlines when she posted pics of herself on Twitter going topless around New York City in order to protest Instagram's anti-nudity policy.

... Clearly, Rumer's just being a supportive sister!

Rumer paired the statement tee with a black maxi skirt and a black blazer, sweeping her pink hair to the side.

What do you think of Rumer's bizarre tee, is it tacky or terrific?
