Vice President Kamala Harris was officially inaugurated on Wednesday, making her the first woman, first Black person, and first Asian person to serve in the role in the country's history. 

To mark the historic event, thousands of Black women broke out their finest pearls and some even took to social media to share their inauguration 'fit. 

Pearls are specifically significant because Harris is a member of the Alpha Kappa Alpha sorority, which calls its founders and members "pearls." Alpha Kappa Alpha is the oldest Black Greek-lettered sorority in the country and many of its 290,000 members across the world took the occasion to wear their pearls.

Harris herself wore a special set of pearls during the inauguration. 

Even non-members of the sorority honored Harris by wearing pearls. Hope Aloaye spoke to TODAY about a Facebook group she started that popularized the idea of wearing pearls on Inauguration Day. 

The group now has more than 400,000 members, with hundreds of Black women sharing photos of themselves wearing pearls with family members. 

"I equated the pearls to women (because) we go through a lot of things, but we still come out shining. Pearls are every color, shape, size. It doesn't matter… I just thought that was a beautiful thing," Aloaye said.

"I wanted a group that was inclusive because we already have so many other things that are so divisive in this country, especially right now," Aloaye added, noting that ahead of Wednesday, members of the group offered to donate pearls to those without them so they could participate. 

Others used the day to promote wearing pearls and the infamous Converse Chuck Taylor shoes that Harris has become known for wearing. 

Rep. Barbara Lee wrote on Twitter that she was wearing pearls from Shirley Chisholm's goddaughter, noting Chisholm's groundbreaking work as the first Black woman elected to Congress, the first Black candidate for a major party's nomination for president of the United States, and the first woman to run for the Democratic Party's presidential nomination.

She later appeared on MSNBC and said Chisholm's work was why she and Harris made it as far as they did in their careers.

"I am wearing Congresswoman Shirley Chisholm's pearls…I am feeling Shirley Chisholm's happiness and spirit," she said.

"This is long overdue, but about 50 years after she was elected and ran for the presidency this time has finally come," she added. 

In some of her first comments as the nation's vice president, Harris spoke about Chisholm.

"Shirley Chisholm created a path for me and for so many others. Today, I'm thinking about her inspirational words: 'I am, and always will be a catalyst for change,'" she wrote on Twitter.
