The 64th annual show was held in Las Vegas at the MGM Grand Garden Arena and featured red carpet appearances from Olivia Rodrigo, Doja Cat, and Carrie Underwood, who set the tone in their glamorous outfits. 

They were just a few of the A-listers  who knocked it out of the park, but, as always, there were also a number of fashion fails from stars who turned heads for all the wrong reasons.  

Billie Eilish and Justin Bieber led the list of worst-dressed stars in their oversize looks, with the latter's suit sleeves being so long they covered his hands. 

Bieber, who walked the red carpet with his wife, Hailey Baldwin Bieber, wore a slate-gray suit that looked like it was at least four times to large on him paired with a hot pink knit cap.

While he may have been playing into the '90s trend, some though he went too far. The 28-year-old Peaches singer was mocked on Twitter by people who joked that he wore his 'dad's suit' to the awards show. 

Meanwhile, Eilish's voluminous black frock that looked like a trench coat was draped over her shoulders. She topped off the avant-garde look with chunky sock boots and a pair of futuristic back shades. 

The 20-year-old singer's dress had similar vibes as the enormous ruffled gown that she wore at last week's Oscars, which also earned her a spot on the worst-dressed list.   

H.E.R. suffered a fashion fail in a sequin-covered yellow jumpsuit that looked like it was revived from the disco era. 

The look featured voluminous ombre-colored sleeves and gold sequins. Style aside, the singer's undergarments could be also seen through the sheer fabric. 

Singer Tayla Parx was quite literally dressed in a dinosaur in a bright green two-piece look that featured spikes on her arms, legs, and around her neck. 

She paired the look with a pair of chunky yellow booties that also had green spikes. She held her long braid in her hand to show off the spiked ball made up of hair at the end.  

Singer Alisha Gaddis also pushed fashion limits a bit too far with her headpiece made out of golden branches. Paired with her princess-style gown, she looked like a wood nymph.  

And social media star Kylie Rae Hall showed a little too much skin in a red lace two-piece featuring two high slits on each of her legs. The 29-year-old's low-cut red underwear could be seen through the sheer lace fabric

Victoria Evigan, one half of the husband and wife musical duo Elephant Heart, drowned her figure in a bright orange and yellow ruffled frock featuring plenty of tulle and gold tassels. 

Her black bandeau top and yellow biker shorts featuring a lace hem were visible from the sheer fabric. 

The gown also came with a political message. When she turned around to kiss her husband, Jason Evigan, she revealed the back of her dress had the words 'Love is the Weapon.' 

Meanwhile, musician Dillon Francis didn't seem to make an effort at all. 

He showed up on the red carpet wearing a T-shirt, black skinny jeans, and black and white checkered Vans. He also carried a plastic Walgreens bag filled with snacks and posed with his ticket to the show.  

Yola took her love for purple to the extreme with her violet gown that was trimmed in fur. The musician's gown featured purple fur gloves with long rhinestone-encrusted spikes attached to the ends. 

She also dyed her long hair purple to match so that she was literally wearing head to toe purple.
