Ariana Grande’s debut ‘Wicked’ tour outfit was a custom Vivienne Westwood pink ballgown and butterfly choker in tribute to Billie Burke’s Glinda.

Ariana Grande has not shied away from wearing pink for the last year in an effort to channel Glinda the Good Witch in the forthcoming film adaptation of Wicked. She's been wearing endless dresses and more casual outfits with varying shades of pink, but her most recent gown might be the most Glinda take so far.

Ariana Grande leaned into method dressing as she stepped out with Ethan Slater in Sydney, Australia. Ahead of the Wicked premiere, the 7 Rings singer was spotted exploring the city while wearing Glinda pink – and her boyfriend on her arm.
