The 2015 Grammy Awards went down at the Staples Center in Los Angeles on Sunday -- and music's biggest names brought their fashion A-game to the red carpet.

Taylor Swift owned the night in her teal high-low Elie Saab gown, which she paired with purple heels and matching emerald jewelry. The 25-year-old beauty styled her shoulder-length tresses straight and rocked a matching green smokey eye. We love the color on the "Blank Space" singer and the dress fits her like a glove.

Gwen Stefani looked like a true rock star in her Atelier Versace jumpsuit. We love the spiderweb detail of the corset and the 45-year-old's bouffant updo and nude makeup were perfection with the sexy number. Does the No Doubt singer ever age?!

And Katy Perry finally got it right this year!

The "Roar" singer sparkled on the Grammys red carpet in her gorgeous winter white rhinestone-encrusted Zuhair Murad midi dress. We love all the diamond details and Perry's wavy lavender locks really added a fun pop of color to her look.

But these ladies weren't the only stunners of the night -- click "Launch Gallery" above to see more of the best dressed stars from the 2015 Grammy Awards!
