The 2016 GRAMMYs was full of memorable red carpet looks -- including a risk-taking Taylor Swift in a skin-baring Versace number and a leggy Carrie Underwood showing off her gorgeous Valentine's Day gift from her hubby -- but they can't all be winners. Check out who topped our best and worst dressed lists at music's biggest celebration!

First, let's start with the stars who looked sensational on the red carpet.

Selena Gomez looked radiant and all grown-up in a sparkly purple Calvin Klein gown.

"I think for the GRAMMYs red carpet we saw two totally different vibes," ET correspondent Joe Zee says. "We saw a lot of black on the red carpet that was actually very conservative and very quiet and subdued, and then you saw bright colors and over-the-top, and I have to say, some of my favorites were more sort of elegant looks. I love Selena Gomez in her Calvin Klein."

Not to be outdone by her bestie, Taylor Swift went for a show-stopping look in a bright coral Versace tube top and a fuchsia skirt. Clearly, the "Out of the Woods" singer felt confident in the edgy style, and her Anna Wintour-like bob.

"I actually think her look by Versace is very different for the red carpet, very different for her," Zee comments. "And I think we're gonna get a lot of people who are gonna love it, and people who are gonna hate it."

Carrie Underwood also won the night in a strapless black Nicolas Jebran dress, which showed off a whole lot of toned leg. She also gave her look a sweetly personal touch, rocking a gorgeous diamond necklace her husband, hockey pro Mike Fisher, gave her for Valentine's Day.

"I've seen Carrie grow up since she was a contestant on American Idol and I think she just really gets it," Zee says of Carrie’s always killer style. "She gets what this is about, and she's so phenomenal, and tonight when she was wearing that black dress and diamonds that her husband bought her -- I was like, 'Nobody on the red carpet wears diamonds she owns, how is that even possible?' But of course, she's Carrie Underwood."

And now for the stars who didn't fare so well on the red carpet.

Model Bella Hadid disappointed in a black Alexandre Vauthier cut-out dress, which turned out to be one of the most boring of the night, despite its plunging neckline.

Meanwhile, singer Tove Lo gets props for her interesting makeup, but her sheer black dress looked sloppy for the occasion.

Finally, country singer Cam rounds out our top three worst dressed of the night, giving us all Big Bird vibes with her bright yellow feathery Georges Chakra dress.
