Interested in Hillary Clinton?Add Hillary Clinton as an interest to stay up to date on the latest Hillary Clinton news, video, and analysis from ABC News.
Rather, the Democratic presidential candidate's white Ralph Lauren pantsuit sent the message.
Clinton has worn Ralph Lauren's designs often since kicking off her campaign. For example, she wore a cobalt blue Ralph Lauren suit for the campaign's opening rally last year in New York City.
But it's her choice of color — not designer — that's significant.
"The choice of a white suit for Wednesday's debate harkened back to the not-so-distant past, when suffragists wore white to promote their struggle to gain the right to vote," Booth Moore, a senior fashion editor for The Hollywood Reporter and Pret-a-Reporter, told ABC News moments after Clinton took to the debate stage at the University of Nevada.
Moore added, "It also serves as a reminder to voters, during a time when Trump has been under fire for lewd comments and accused by 10 women of inappropriate sexual behavior, that she is the women's candidate."
There's even a connection between Clinton's wearing white and being a candidate.
Israel Waismel-Manor, a senior lecturer at the University of Haifa's school of political science, told ABC News, "'Candidate' comes from the Latin word 'candidatus,' which means 'white robed.' It signifies you are clean, have nothing to hide, pure. Trump is the opposite."
Trump's ensemble — a dark suit, white shirt and red tie — also sent a message, Moore said.
"The red tie is about the most traditional inside-the-Beltway GOP male power uniform you can get," she said. "Seems to be trying to show he belongs."
