The red carpet is clearly no longer a place for just glamour. Sunday night's Golden Globe Awards red carpet demonstrated a powerful statement as some of Hollywood's most powerful ladies donned all black. (Men joined in as well, choosing black shirts instead of white to go with their tuxes. Many wore red lapel pens in solidarity.)

These women were all supporting the Time's Up campaign, which as already raised $15 million for their Legal Defense Fund since Jan. 1. The money will help working women fight for sexual harassment charges and equality parity.

But the black on black fashions weren't homogenous: By 6 p.m., the Beverly Hilton was a seas of sheer, floral and off the shoulder gowns and pantsuits. Michelle Williams was among the first to arrive with #MeToo Founder Tarana Burke, a former Philadelphia native.

Meryl Streep,  in a deep, off-the-shoulder gown, in black glasses looked very Miranda Priestly. She arrived with Ai-jen Poo, director of National Domestic Workers.

Instead of asking who the designers were wearing — although it was revealed that Kelly Clarkson's gold-sleeved black ballgown was designed by Christian Siriano — the questions was, "Why are you wearing black?"

The answers were moving and raw.

"It's about power and balance," Streep said.

Debra Messing's black pantsuit was peculiar, but her message was clear.

"I'm wearing black to thank and honor all of the brave whistle blowers who came forward," Messing said. "It's an incredible initiative. Time is up."

Messing also called out E! while speaking to host Giuliana Rancic, referencing former E! News host Catt Sadler, who quit the network after she said she was being paid less than her male colleagues.

"E! doesn't pay co-hosts the same as male co-hosts," messing said.  "I miss Catt Sadler. "We stand with her  … Women are just as valuable as men."
