The pair swapped their trademark green and pink colours, featured heavily during their press tour, for those worn by their characters Elphaba and Glinda during the Emerald City musical number of One Short Day in the theatre performance.
Erivo was styling a black velvet sleeveless dress featuring tulle embroidered with light pink rhinestones, paired with long black velvet gloves and a matching headpiece from the Schiaparelli autumn/winter 2024 collection.
Grande opted for a lemon yellow silk gown with extra layers of tulle flowing in a train behind her at the Royal Festival Hall, Southbank Centre in London on Monday. She styled the ruched organza with a pair of John Lennon-style tinted glasses.
