Take a Look at all the Stars Who Rocked the Time's Up Pin on the Golden Globes Red Carpet

On Jan. 1, a group of 300 women came together and announced Time's Up, a new initiative to "fight systemic sexual harassment in Hollywood and in blue-collar workplaces nationwide," and they took it a step further by creating a pin that stars wore on the Golden Globes red carpet. Almost all of the female stars on the red carpet wore black on the red carpet in solidarity but it was actually the men who rocked the pin more than the women.

Reese Witherspoon asked Arianne Phillips, a costume designer and stylist, to design the pin in a private meeting, according to The Hollywood Reporter. "We were up against the holidays, but I said I could do it, and the first person I called was my partner-in-crime, [Los Angeles jewelry designer] Michael Schmidt," Arianne said.

The duo teamed up with a few others to design the Time's Up logo and had 500 manufactured in just two weeks. "I met so many great women, and it was such an honor to be called to action," she went on to say. Take a look at the pins ahead and all the stars who wore it with pride on the red carpet.
