The Best (and Worst!) Red Carpet Looks at the 2017 GRAMMYs

ET's rounded up the most memorable looks from music's biggest night.

Yet again, the fashion at the 59th Annual Grammy Awards was far from forgettable!

While many stars pulled out all the stops with their red carpet looks on Sunday night, rocking dazzling couture gowns paired with stunning jewelry, there were a few A-listers who seemed to miss the memo.

Now, ET’s rounded up our favorite (and not so favorite!) looks from music's biggest night.

And what would an awards show carpet be without at least one pop star dressed in gold? Demi Lovato pulled off the popular hue in a daring Julien Macdonald knit cutout gown. She kept full focus on her dress by wearing her hair down and rocking bronzed makeup.

While we usually love anything Jennifer Lopez steps out in, we have to admit, this was not one of our favorite looks from the Shades of Blue star. The thigh-high slit on her lavender Ralph & Russo gown totally worked, but the neckline, which featured a tulle bow, was distracting.

Going braless and wearing bright blue Christian Wijnants silk pajamas, Halsey seemed to be taking a cue from TLC's "Creep" music video with this look. Unfortunately, her version of the comfy ensemble landed a spot on our Worst Dressed List.

Although there were quite a few fashion missteps at the GRAMMYs, we don't think anyone turned heads more than Girl Crush, who wore something that looked like it was created from the plastic balls you'd find in a McDonald's PlayPlace ball bit.
