From Cosmopolitan Magazine:

“But mostly it served to showcase Harris’s signature pearls, which are arguably the most defining part of her public image. The vice president has become known for her pearls, a symbol of her membership in Alpha Kappa Alpha, the first Greek-letter sorority founded by Black women at her alma mater Howard University. For the inauguration, Harris wore a pearl necklace by Wilfredo Rosado, a Puerto Rican designer who worked for Giorgio Armani and Andy Warhol. The elliptical chain link, described by the brand as a “bold yet feminine statement,” featured South Sea pearls with small diamonds floating between. “When I think of hip-hop style, the artists are always wearing heavy chain links, and I decided to combine that with pearls,” the designer told Town & Country.

More so than any one necklace, Harris’s pearls have come to mean something special to her supporters. They wear them to honor her, much like fans of Ruth Bader Ginsburg sport her statement collars. A Facebook group called “Wear Pearls on January 20th, 2021,” amassed more than 450,000 members. On Instagram, the hashtag #PearlsForKamala was filled with women celebrating her swearing-in. And isn’t that the most powerful use of fashion? Crafting a visual legacy that can be shared and enjoyed widely? I, for one, am excited for the next four years.”
