The best and most daring outfits celebrities wore to the iHeartRadio Music Awards

Designed by Robert Wun, her outfit had a floor-length pleated skirt and a blazer top with cape-style sleeves.

She wore it with a diamond necklace, statement earrings, and natural-looking makeup.

She paired the long-sleeved look with semi-sheer tights, platform sandals, and a small handbag with "Baby Girl" written across it in rhinestones.

Her Alessandra Rich gown was crafted from black velvet, with a row of feathers lining its off-the-shoulder neckline.

The dress retails for $2,285.

She also wore a tan fuzzy coat, chunky boots, layered necklaces, and '90s-style sunglasses.

The casual look is a departure for the musician, who has recently worn claw-shaped boots, cutout dresses, and red crystals covering her body.

Speaking with Insider on the red carpet, Kendall Schmidt joked that they each aimed to wear "the hottest thing you can."

"We said, 'Guys we should look hot on the carpet,' and that's what we did," he said.

"We thought we'd go colorful and warm," James Maslow added.

To accept the iHeartRadio innovator award, Swift donned an Alexandre Vauthier jumpsuit complete with long sleeves, shoulder pads, and a dazzling hood.

He paired sparkling trousers with a mesh, button-up shirt and a blazer with sharp shoulder pads.

Kravitz also wore a mix of diamond and chain necklaces, pointed boots, and dark sunglasses.

Designed by Julien Macdonald, her blue dress had a single long sleeve with a sharp shoulder pad and a cutout that extended across most of its bodice.

The sparkling gown also had a thigh-high slit that revealed her matching blue sandals.

He wore a green Nanushka puffer coat, leather pants in the same shade, and a T-shirt that said, "I come back stronger than a '90s trend" — a lyric from Taylor Swift's song "Willow."

"I'm a big Taylor Swift fan. I've always been a big fan of hers," he told Insider on the red carpet as he pointed to his shirt.

But as for the rest of his outfit, Flavor Flav said, "I just put it on and go."

She wore a black Rodarte halter dress with a flower appliqué at the chest and chunky shoes.

Her outfit, designed by PatBo, included a halter crop top encrusted with pearls, and a high-waisted skirt with two cutouts at her hips.

She wore the look with lace-up heels, sparkling jewelry, and long nails.

The Paco Rabanne look was straight off the runway.

The bralette top was crafted in a chainmail style and was connected to a matching skirt via a PVC bodice.

She wore a bustier top underneath a satin blazer, leather belt, and ankle-length skirt.

Clarkson completed the look with steel-toe boots and long diamond earrings.

She wore a Julien Macdonald gown made from black lace, with cutouts across the shoulders and chest.

The musician also rocked diamond rings and oversized hoop earrings.

The sleeveless look had a navy-blue top and a brown skirt, the latter of which was covered in beads and had a thigh-high slit.

"I just wanted to try to bring the spirit of one of the greatest of all time: Prince," Jacoby Shaddix told Insider about his purple suit. "And the Sacramento Kings."

Jerry Horton, on the other hand, said he wore black because he wanted to look like a "rock star."

The Brazilian singer told Insider that her purple outfit was designed by Claude Kameni.

"She's bringing all these beautiful African patterns and blowing up right now," Gabrielly said. "I just think it's a beautiful shape — and I love shoulder pads."
