If you notice a lot of stars accessorizing their black couture with an enamel pin during Sunday's Golden Globe Awards, you might be wondering why. And the red carpet accessory actually has a very powerful message behind in.

The small pin, which features the phrase "Time's Up" in bold white lettering, is to promote the Time's Up initiative, a sexual harassment prevention organization launched on Monday by an extensive group of powerful women in Hollywood, including Reese Witherspoon, Shonda Rhimes, Eva Longoria and Kerry Washington among others.

According to The Hollywood Reporter, Witherspoon, who is nominated for her role in Big Little Lies, asked costume designer Arianne Phillips to design the accessory.

"We want all survivors of sexual harassment, everywhere, to be heard, to be believed, and to know that accountability is possible. We also want all victims and survivors to be able to access justice and support for the wrongdoing they have endured," the women behind Time's Up wrote in an open letter earlier this week.

The Time's Up pin isn't the only way stars will turn their Globes fashion into political statements. Many also are choosing to dress in black as a means of showing support for all the victims of sexual harassment and assault that have come forward in the wake of the New York Times expose of Harvey Weinstein, which detailed several allegations against the prolific producer. Since then, many men and women have come forward to share their own stories about sexual harassment and assault in Hollywood, with many of these allegations leading to the firing of several of the men in question, including Kevin Spacey, Louis C.K. and The CW producer Andrew Kreisberg.

The Golden Globes air Sunday at 8/7c on NBC.
