Siwa stunned everyone at the 2021 American Music Awards when she changed her look by wearing an off-the-shoulder black gown instead. She also ditched her usual high ponytail and let her hair down.

"I am in a dress and heels the first time in my life," she told People. "When I knew I was coming to the AMAs, I was like, 'Oh, what am I gonna wear,' because I have had this transition while being on Dancing with the Stars where I've gone from dressing like I normally dress to looking more adult. And I want to branch out of my comfort zone, and so today we went for a dress. I got some heels on."

The now-20-year-old singer and danger debuted a daring look at the iHeartRadio 102.7 KIIS FM's Jingle Ball 2021 in Inglewood, Calif. She arrived in her black blazer top with a sparkly silver bow without wearing anything underneath.

Siwa paired the daring top with black leather shorts and heels.

"It's a little T-to-the-bow tonight, a little more adult T-to-the-bow bow," Siwa told E! News about her outfit. "My mom went shopping. She pulled a few things out of a bag and, immediately, I knew, this is the one for tonight. It's the one."

Siwa attended the Kershaw's Challenge 10th Annual Ping Pong 4 Purpose's 2023 Charity Event Celebrity Tournament at Dodger Stadium.

After years of wearing bright-colored clothes, Siwa surprised the public with her black makeup and attire at the 2024 iHeartRadio Music Awards. She sported a similar style when she promoted her new song "Karma" in West Hollywood.

"Everyone is making such a big deal about her rebranding. JoJo is doing incredible dancing with a lot of paint on her face. It used to be stars and rainbows and pink and lavender and turquoise, and now it's black," Miller said of Siwa's new style. "It's still her doing incredible dancing, so I don't know if it's so much as a rebranding or just maturing, getting older, wanting to show another side of her."
