Katy Perry, Heidi Klum and Kacey Musgraves among worst-dressed celebs at iHeartRadio Music Awards
From Katy Perry's grandma look to Heidi Klum's ongoing confusion with her looks, here's the worst dressed celebrities that walked the iHeartRadio Music Awards red carpet

Every year, the who's who of the music industry gather together to hit the red carpet at the iHeartRadio Music Awards wearing their finest. On Thursday, celebs attended the 2019 iHeartRadio awards wearing their maverick and quirkiest best at Microsoft Theater in Los Angeles. While many rocked the carpet with their style, others might want to give it a second thought before posting their pictures on Instagram.
In case you missed, we compiled a list of those who really missed the mark at hitting the best notes with their ensemble?
Bebe Rexha

Bebe Rexha was clearly trying to channel the spirit of Zorro on the iHeartRadio Music Awards carpet, but somehow we have absolutely no idea why. She rocked a black jumpsuit with a plunging neckline and the odd hat atop her head. Though we weren't crazy about her odd headwear, we can't deny that the star's smokey eye and nude lip were nothing less than stellar.
Betty Who

The singer essentially wore a sleeveless bodysuit, so we're unsure why Betty Who even bothered with the completely sheer long sleeves and pants. The star finished off the odd choice of costume with a pair of silver heels for an extremely underwhelming look.
Drake Bell

Drake Bell probably had to be the worst dressed guy on the iHeartRadio Music Awards carpet ever. The star should have known his fate was sealed as soon as he stepped out in this unfortunate tan, plaid suit, teamed up with a red patterned tie and Gucci footwear to the music event.
Heidi Klum

We really can't figure out what's worse - Heidi Klum's hideous flowy leopard dress or those awful over-the-knee boots. Even though animal prints are making a huge comeback, this look is just not pleasing enough for a red carpet, so we think we're going to call this one a draw.
Madison Beer

Madison Beer for some reason decided to wear a white strapless frock by Ester Abner, complete with a daringly high hemline and a pleated panel down the middle. Sadly, we weren't crazy about that tiered asymmetrical cut and the iridescent Casadei pumps she paired with it.
Katy Perry

Katy Perry was dressed like our grandma in the '50s! The singer donned a strange checkered dress by Paskal that gave a tiny glimpse of a blue bra underneath and accessorized it with a headband, a thick black belt at the waist, and thumb-less black leather gloves. All for no apparent reason. Perry opted for Mary Jane style heels (by Katy Perry Collection, obviously!) with socks. She donned chunky dangling earrings, a bright red lip, and pink eyeshadow in a look that kept us scratching our heads the rest of the night.
Kacey Musgraves

Kacey Musgraves totally missed the mark with this mini dress. Though we've been really into the country crooner's style as of late, this David Koma dress left us completely underwhelmed with its tiered ruffles and odd color combination of black and green. Kacey paired the frock with her signature straight hairstyle and simple makeup.
Billie Eilish

Billie Eilish stepped on the carpet in a gothic Sailor Moon inspired getup, pairing knee-length shorts with an oversized jacket, that we're pretty sure came straight out of the singer's neighborhood teen mall. Mounds of edgy rings, funky studded bracelets and a panoply of necklaces adorned the singer's attire. She also debuted a darker hairstyle, having most recently rocked an icy blue hue.
