The 33-year-old rapper slipped into a strapless mermaid dress for her after-party at The Grand nightclub in Boston on Thursday, fresh off a stop on her Little Miss Drama Tour at TD Garden.
The curve-hugging design — plucked from London-based label Di Petsa’s fall 2026 runway, which debuted at London Fashion Week in February — was printed with a seashell bra and shimmering gray-and-black scales.
She styled the design with towering silver sandals as she strutted backstage at the arena.
Fan-shot videos posted to social media show the “Bodak Yellow” rapper dancing atop the bar barefoot after ditching her heels. She captured the view from above on Instagram Stories with the caption “The Aftie.”
The outing comes as Cardi stays booked on all fronts. Her hair care brand, Grow-Good Beauty — developed with Revolve Group and rooted in the rapper’s own DIY hair treatments — is set to launch April 15.
She’s also been riding a wave of headlines since her split from New England Patriots wide receiver Stefon Diggs after Super Bowl LX in February. The two, who welcomed a son in November 2025, unfollowed each other on Instagram shortly after the game.
None of that appears to be slowing the rapper down. Boston declared April 2 “Cardi B Day” ahead of her sold-out TD Garden show, and her 35-date arena tour — her first — wraps April 18 in Atlanta.
Di Petsa, known for its signature “wet look” dresses favored by the likes of Bella Hadid, Doja Cat and SZA, continues to build a celebrity following with its body-conscious, mythology-inspired designs.
