It may have been Offset’s birthday, but the night was all about Cardi B!The “Bodak Yellow” rapper slayed the fashion game at her fiance’s birthday party, a Met Gala-themed soiree called “The Set Gala,” held at The MacArthur in Los Angeles on Wednesday.Cardi stunned in a white-and-gold asymmetrical, semi-sheer Nicolas Jebran dress that was covered in diamonds and Swarovski crystals. She wore her dark, pin-straight locks down, and accessorized with long fringe earrings, strappy gold sandals and, of course, her jaw-dropping engagement ring.Offset — who turned 26 on Thursday — was pretty dapper himself, blinging out in a sparkly jacket, layers of chains and black leather pants. Appropriately, he not so shyly deemed himself and his lady “R O Y A L T Y” on Instagram.
