Ariana Grande made a wickedly good arrival for her first-ever appearance at the Oscars.

Stepping onto the red carpet tonight outside of Los Angeles’s Dolby Theatre, the “We Can’t Be Friends” singer embodied Wicked’s Glinda in a cotton-candy pink column gown, a custom Giambattista Valli Haute Couture design featuring intricate ruching from the top to the bottom. At the waist were pillowy cloudlike attachments, which extended into a dramatic train that trailed behind her. As if that weren’t enough, the look was topped off with a huge pink gemstone-encrusted necklace and matching drop earrings from Tiffany & Co.
