However, a few stars — we're looking at you, Joy Villa — took fashion risks that fell flat.
The controversial singer, who has made more headlines for her style choices than her songs, wore an attention-grabbing dress to show her support for President Donald Trump's plan for a proposed border wall between the United States and Mexico.
That wasn't the only headline-making moment on the red carpet. Singer Ricky Rebel also made a political statement at the awards show, wearing a red-white-and-blue jacket that said "Keep America Great!," "Trump" and "2020."
Several adorable couples engaged in PDA for photographers before entering the awards show. Singer Meghan Trainor, in a glamorous white jumpsuit, got a kiss from her new husband, Daryl Sabara, as the adorable newlyweds posed for pics.
Alex Rodriguez and Jennifer Lopez, Evan Ross and Ashlee Simpson, and Alicia Keys and Swizz Beatz were also making googly eyes at each other on their way to the Grammys.
But let's face it: It's the over-the-top fashion looks that had everyone online talking.

BEST: Miley Cyrus
The newlywed stuns in a black suit that may be her hottest Grammys look of all time.
The red carpet stunner, who arrived at the Grammys already having won an award for Best Song Written for Visual Media for "Shallow," shines in a silver metallic gown with a thigh-high slit.
The conservative singer is no stranger to red carpet controversy. This year she is trying way too hard to get attention with a "build the wall" dress designed by Designers Allinger of Desi Designs, complete with barbed wire and a spiky headpiece.
Hector Buitrado and Andrea Echeverry, from the Colombian rock band Aterciopelados, pay homage to the Grammys with what can only be described as gramophone nipples.
The singer, who is nominated for Best New Artist and Best Collaboration for "Meant to Be" with Florida Georgia Line, looks radiant in a red Monsoori dress with a diamond necklace, earrings and bracelet.
