Happy Inauguration Day! In honor of this great and historic day, three of the country's most influential women chose to wear the same, very important color: purple. Soon-to-be Vice President Kamala Harris (opens in new tab), former First Lady Michelle Obama, and former First Lady and Secretary of State Hillary Clinton are wearing this historically significant color. Even Senator Elizabeth Warren opted for a purple scarf!

So why is purple so important, for one thing, it represents bipartisanship. It literally mixes the red of the Republican Party with the blue of the Democratic Party. This can be interpreted as symbolic of Harris's perspective as she begins this next chapter, and perhaps of her desire to unite the two camps.

Second, it is also the color of the suffrage movement. Purple is the color of loyalty, constancy of purpose, and unwavering steadfastness to the cause." White, the symbol of purity, symbolizes the quality of our purpose, and gold, the color of light and life, is as pure and unwavering as the torch that guides our cause," wrote the newsletter of the National Women's Party of America (opens in new tab). Harris chose white to deliver her victory speech in November (opens in new tab), after Biden-Harris was officially elected.

Harris, the first black, South Asian-born woman to serve as vice president, chose to wear her signature purple design by two black American designers, Christopher John Rogers (opens in new tab) and Sergio Hudson (opens in new tab), along with her signature She chose pearls (opens in new tab), a color that CNN's Abby Phillip also noted was a nod to Shirley Chisholm, the first black woman elected to Congress, whom Harris had previously honored (opens in new tab).

Hillary Clinton also chose purple (designed by Ralph Lauren, who also made the suit she wears today) for her impressive 2016 concession speech (opens in new tab), hoping to elect the first woman to the White House, and the pantsuit to vote for her She spoke to the millions of disappointed women who wore them and sent a powerful message.
