It was a busy Sunday full of fashion, with the 2016 Academy of Country Music Awards in Las Vegas and the iHeartRadio Music Awards in Inglewood, California, falling on the same night. Read on to find out which stars rose above their peers to top our best -- and unfortunately, our worst -- dressed lists!
First, let's start off with our fashion superstars of the evening.
The 33-year-old country singer is pretty much a staple on our best dressed lists and for good reason. Carrie, once again, hit it out of the park at the ACMs, showing off her super slim figure in a delicate Davidson Zanine nude gown.
The 23-year-old "Hands to Myself" singer made a bold choice with this orange cut-out Mugler jumpsuit at the iHeartRadio Music Awards, and it paid off. Selena nailed the sophisticated look, while still staying on trend.
All eyes were on the 32-year-old country superstar when she made her red carpet debut with her new boyfriend, singer Anderson East, at the ACMs, and she definitely didn't disappoint. Miranda looked super sexy in a yellow Christian Siriano gown showing a whole lot of cleavage and leg thanks to its thigh-high slit, but it's her hot pink Joyce Echols heels featuring a mini gun and holster that took her outfit to the next level.
.... And now for the stars who didn't fare so well on Sunday.
The 25-year-old rapper has great abs, but even her killer bod couldn't excuse this bizarre Off-White c/o Virgil Abloh outfit consisting of a busy one-shoulder crop top and wide-leg, high-waist pants she wore to the iHeartRadio Music Awards.
We know the 31-year-old pop star was honoring the legendary Dolly Parton with her outrageous Jeremy Scott Couture outfit at the ACMs -- complete with hot pink cowboy boots -- but this completely over-the-top look crossed the line into costume territory.
We wanted to love Demi's black-and-white Alexander McQueen suit at the iHeartRadio Music Awards -- and the edgy choice would have been perfect for the 23-year-old "Confident" singer -- but the ill fit of the loose, too-long trousers just can't be ignored.
Although both Demi and Iggy landed on our worst dressed list of the night, at least the two besties had a great time having a girls' night out on Sunday.
"We're gonna sit together. We're messing up the seating arrangement," Iggy told ET on the red carpet about her longtime pal. “I think it's more fun to make it like, a girls' thing or a friends’ thing. It's just more fun, more laughs."
