Olivia Rodrigo channeled the iconic cartoon character Betty Boop on Saturday while attending Kendall Jenner's 818 Tequila Halloween party in Hollywood.

The "good 4 u" singer, 19, wore her hair in black pin-up curls and nailed the iconic look with a tomato-hued strapless dress, matching purse and garter belt, plus black knee-high stockings and black patent Mary Janes.

It's not the first time that Rodrigo has rocked a bold look. Earlier this year, she attended the Los Angeles premiere of her new Disney+ documentary, Olivia Rodrigo: Driving Home 2 U wearing a black corset top from Fancí adorned with silk bows.

In June, the singer and her best friend Iris Apatow took their fashion talents to Paris, in between Rodrigo's sold-out Sour Tour shows.

In snapshots of the French city and a fun throwback photo of herself sporting a Paris T-shirt as a child, Rodrigo also gave followers a glimpse of her vacation style, which she coordinated with Love star Apatow, 19, who accompanied her on the Parisian trip.
