Olivia Rodrigo is requesting something from her fans.
The singer, 19, sent out a message on Twitter on Friday, encouraging fans who would be attending a show in Detroit, Michigan, on Saturday evening to dress up in “prom costume” to honour opening act Gracie Abrams’ final night on the tour.
“You’re the ones. I wanted to do something special for Gracie’s final concert in Detroit tomorrow “Rodrigo began her post on social media.
“Since it’s prom seasonnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn “Would you be interested in joining us? What should I wear to the prom?”
Since the show’s inception on April 5, Abrams, 22, has acted as Rodrigo’s Sour tour opener. When the performance comes to Radio City Music Hall in New York City next week, she will be replaced by Holly Humberstone. (In the meanwhile, Rodrigo’s San Francisco tour will have Chappell Roan as the opening act.)
When the Sour tour heads overseas to Europe this summer, between June 11 and July 7, Baby Queen will take over.
Rodrigo told PEOPLE at the start of her Sour tour that she was “stoked” to share her music with her fans in person.
“I’ve been attending rehearsals on a daily basis. It’s a lot of fun. I’m really looking forward to getting on the road “‘At the moment,’ she added. “It’s been a strange experience releasing my music at peak COVID, when everyone is so secluded from one another.”
“The music went crazy,” Rodrigo added, “and I never got to see it with real people.” “So, I’m really looking forward to seeing all of the individuals who have been impacted by the music in person and just singing and dancing and having a good time with all of these new friends. I’m quite excited.”
The “Good 4 U” singer also told PEOPLE that her guitar and lavender-scented candles are her go-to tour staples, which she hopes will “make it seem more homely.”
On July 7, Rodrigo’s Sour tour will come to a close at the Eventim Apollo venue in London, England.
