First holiday party of the season! Taylor Swift, Ariana Grande, and more attended KIIS FM’s 2014 Jingle Ball in L.A. on Friday, Dec. 5. But before Swift opened up the show with her hit “Blank Space,” the stars showed off their finest threads on the Staples Center’s red carpet.

Here, Us Weekly has rounded up some the best looks of the night. See what the performers wore below:

Taylor Swift
The singer’s “style” was on point as she wore a strapless Romona Keveza A-line cocktail dress, which featured a black silk crepe bodice and gold skirt. Before hitting the stage, she made a quick change into a black sparkly skirt and matching crop top. Some of her set included “Blank Space,” “We Are Never Ever Getting Back Together,” and “Love Story.”

“I have laryngitis and will need your help singing tonight let me hear you scream!” she told the crowd. She also acknowledged her three Grammy nominations before singing her “Shake It Off” hit. “I would like you to know that this had been my favorite year of my entire life and I turn 25 next year and it was a nice early birthday present,” she said.

The music producer swapped his infamous Vivienne Westwood Grammys hat for a smaller version for the big night. He performed “Drop it Like its Hot” with Snoop Dogg backup tracks and his repeat-worthy hits “Get Lucky” and “Blurred Lines.”

Jealous of his skills? The singer was accompanied by an organ player when he sang a gospel version of “Jealous.” He looked smoldering in a black leather jacket (cardigan on red carpet!) and matching pants.
