Double duty! Katy Perry stunned with a rich, red hair color at the Harper’s Bazaar Icons event in collaboration with Kit and Ace on Wednesday, Sept. 16. But that hairstyle didn’t last long as she was spotted with a bubblegum-pink wig later that very same night.

The "Roar" singer's first entire look gave off a Jessica Rabbit vibe thanks to old Hollywood curls, a beaded gown by Saint Laurent with a high slit, and platform heels. But her post-party wear was more akin to a go-go dancer. Stepping out of her car later on, the Part of Me star, 30, rocked a short black sheath dress with star-motif stockings and, most noticeably, hot pink hair.

But Perry wasn’t the only A-lister in attendance. Kendall Jenner (rocking new nipple hardware), best friends and fellow models Gigi Hadid and her sister Bella Hadid took to the carpet as a trio. Jenner, 19, wore a long, white Calvin Klein gown, while Gigi stunned in a gold and white Balmain mini, and Bella turned heads in a sexy, black KaufmanFranco number with a cutout back and gold detailing.

Julianne Hough attended the event in a sultry, long-sleeve black gown by Zuhair Murad with an illusion backless design and a thigh-high slit. The recently engaged dancer, 27, finished off the ensemble with, of course, her sparkling engagement ring from Brooks Laich. Going for bold eye makeup, instead of a statement lip like Hough’s pink pout, Kiernan Shipka attended the event in an embroidered navy blue frock, paired with jewel-embellished blue sandals by Giuseppe Zanotti. Also opting for a strapless blue dress, actress Katie Cassidy walked the carpet accessorizing her eye-catching number with a black envelope clutch and gold and black heels.

Flaunting her ample cleavage, Kate Upton stepped onto the scene in a vampy black asymmetrical-hemmed dress, pairing the look with T-strap pumps and a teased-up, bombshell hairstyle. Plus-size model Ashley Graham also opted for a figure-hugging dress that laced up from the bottom. She kept her hair away from her face in a classic half-up style and finished with a deep berry lip color.
