Olivia Rodrigo sparkled on the Grammys red carpet in an optical-illusion dress embellished with hot-pink crystals

• Olivia Rodrigo wore an optical-illusion dress designed by Vivienne Westwood to the 2022 Grammys.
• The dress featured pink crystals that created an hourglass silhouette.

Olivia Rodrigo wore a black satin gown with bold corset detailing and hot-pink rhinestones that created an optical illusion while on the 2022 Grammys red carpet Sunday.

The "Good 4 You" singer, who is nominated in seven categories, walked the red carpet in a Vivienne Westwood dress with matching opera-length gloves. She also wore two pink choker necklaces and black platform stiletto heels.

The gown's most striking detail, by far, was a pattern of hot-pink crystals that created an hourglass silhouette. Rodrigo told "E!" red-carpet host Laverne Cox she was going for "something fun and young."

"It's the Grammys, it's classy," Rodrigo said.

Rodrigo is nominated in the "big four" categories at the 64th Annual Grammy Awards: album of the year, record of the year, song of the year, and best new artist. In 2020, Billie Eilish became the first woman to take home all four awards.

"I could never have imagined this in my wildest dreams, growing up watching the Grammys religiously and the performances on YouTube so many times. To be here tonight with all these incredible people, it's such an honor," she told Cox.
