It’s well documented that fashion trends are cyclical, and on the eve of Election Day a style from the early 1900s is suddenly in again.

Some women are donning white clothes—blouses, dresses, or maybe even a sensible pantsuit—as they head to the polls to vote in the United States election that could put the first woman in the White House.

The pristine aesthetic is an homage to the official color of the U.S. suffrage movement that took place early last century and a nod to the historic nature of the election, which has been largely overshadowed by partisan vitriol and scandals involving Hillary Clinton’s emails and Donald Trump’s alleged sexual misconduct.

Clinton supporters latched onto the #wearwhitetovote movement after the candidate appeared at the third and final presidential debate in an all-white pantsuit. (She also wore white to the final night of the Democratic National Convention.)

Since securing the right to vote, women have—time and again—donned white garments as a show of solidarity and as a way to identify historic achievements.

And there may be lots of white popping up in lines at polling places on Tuesday.

After the final presidential debate, Clinton had lightheartedly confirmed rumors that the late rapper Tupac had influenced her wardrobe choice—the resemblance is remarkable—but an allusion to the suffrage movement makes much more sense.
