As a cultural icon who's created numerous influential moments in 2020, Cardi B served as the inspiration for many Halloween costumes herself, and posted a lot of her fans' tributes on her story. Among those fans was Ciara.
As The Inquisitr noted, the R&B legend created a look for herself and her 6-year-old son to channel Cardi B and her husband, Offset, as well as recreating classic looks from fellow rappers Megan Thee Stallion and Nicki Minaj.
Inspired by Cardi's Invasion of Privacy album cover, she embodied the rapper by wearing a checkerboard-print jacket with matching pants, cat-eye sunglasses, and bright yellow hair. She also included a subtle endorsement of Democratic nominee Joe Biden and Sen. Kamala Harris through the political artwork on her nails.
Ciara's son wore a black denim jacket and T-shirt, a gold-colored chain, earrings, fake dreadlocks, and a pair of sunglasses to resemble Migos rapper Offset. The mother-and-son duo also sang along to Cardi's song, "Drip," in a short video.
Cardi reposted the photos on her Instagram, calling herself a "huge fan."
"I'm gagging! I love it! I'm so hype! I've always been a huge fan of @ciara and became an even bigger fan after I met her! She is the most sweetest and the most nicest person in the world! A true peach! Staying sweet and humble was the prayer!" the musician wrote, acknowledging that the look was a tribute to her.
