Nyong'o, 33, kicked off her solid fashion run at the Los Angeles premiere of Queen of Katwe on Sept. 20. Her lilac gown featured a large cut-out at the chest, pastel-striped piping, and a pleated skirt. She accessorized with a matching headpiece and Grazieka Gems lavender earrings and ring, completing her look with red lips and white nails.
"Feels like yesterday that I read the script for #QueenOfKatwe, a dream to be at our premiere last night!" she captioned a photo of her red carpet turn shared via Instagram.
The next night, she couldn't stop laughing during her appearance on Jimmy Kimmel Live, where she made her mark in a strapless tan ensemble that included a floral printed skirt and turban with the same pattern.
The Oscar winner then went trendy during an official screening of Queen of Katwe by The Academy of Motion Picture Arts and Sciences at the Museum of Modern Art in New York City on Sunday, shining in an off-the-shoulder white dress with black stripes. She kept the look simple, complementing the fun frock with intricate silver hoops and a ring.
Nyong'o continued the vogue streak with a purple printed dress and teal-infused truban during the official opening of the Smithsonian National Museum of African American History and Culture in Washington, D.C on Saturday. She even took a selfie with some of our favorite movers and shakers, including Gugu Mbatha-Raw, Ava DuVernay, Octavia Spencer, and Janelle Monae.
Later that evening, she swapped into an embroidered top (those parrots!) and colorful sequined skirt for the museum's gala, which she attended with her Queen co-star, David Oyelowo, and and Disney executive vice president of production, Tendo Nagenda.
You'd think all those events would be exhausting, but the 12 Years a Slave star stayed on-point during a long day of press on Monday, including stops at Good Morning America and the Sirius XM studio in New York City.
While we couldn't get enough of the gorgeous navy blue dress she wore with a yellow floral headwrap, Nyong'o was all about meeting "Broadway royalty" Kristin Chenoweth.
The delightful actress has proven to be flawless many times before, but we're still (happily) stuck on that beatboxing riff she broke out for ET's Cameron Mathison during the Toronto International Film Festival earlier this month. Check out her skills in the video below.
