Sunday was the biggest night in music. The 57th annual Grammy Awards aired on CBS, bringing together some of the hottest entertainers in the industry. The event awarded the biggest achievements in music for the year, and brought to the stage some jaw-dropping and breathtaking performances.

Sam Smith may have stolen the show with his whopping four wins, but there were plenty other winners on the Grammys red carpet. Here are our top picks for best and worst dressed stars from the 2015 Grammy Awards red carpet:

BEST DRESSED

Taylor Swift stole the show in a stunning teal gown by Elie Saab. Although the dress was floor length, the 25-year-old was able to how off her sexy long legs thanks to a high-low front. The cut also complemented her purple Giuseppe Zanotti heels which provided the perfect pop of color.

Anyone else miss Rihanna’s sexy red carpet looks? The 26-year-old singer showed up late to the Grammys wearing a pink ball gown by Giambattista Valli. Twitter had no idea what she was hiding under there, but Ed Sheeran claims she pulled a bag of M&M’s out of her dress.

Pasties are totally acceptable at the Grammys -- but singer Joy Villa’s orange construction fence dress is all sorts of wrong.
