KIIS FM hosted their Jingle Ball 2014 on December 5th.  As the first celebrity holiday party of the season, this was the first opportunity for many attendees to show off their 2014 holiday fashions.  Let’s take a look at what they wore.

Taylor Swift

Taylor Swift didn’t just attend the ball, she performed a few songs, including her newest hit “Blank Space.” Swift looked stunning in a black knee-length skirt and long sleeve top. The skirt and top both had a glittery finish to incorporate a little holiday spirit, while leaving her midriff bare.  She then finished the look with a pair of  classic looking black heels.  As always, she succeeded in making the look both glamorous and sexy!

Nick Jonas and Demi Lovato

Nick Jonas shared the stage not with his brothers, but with Demi Lovato.  He went with a pair of casual pants, two layered shirts, and a black leather jacket. Lovato matched him with a black sleeveless top and a pair of tight jeans. Both took the stage solo as well, with Jonas losing the black jacket and unbuttoning his grey shirt to reveal the white tee underneath. While he looked great in both styles, we truly loved the way he rocked it out with Lovato.

Sam Smith 

Sam Smith had the audience sing along with his performance of “Stay With Me.”  He looked dashing in a pair of checked pants, black button up shirt, and a black jacket. The takeaway from Sam's look was how he was able to add personality to a handsome, formal style, by adding in some fun checkered pants. He didn't go over the top, he simply created a combination that worked well when paired together.

Nick Cannon

Nick Cannon also looked great in his coordinating pants and formal vest.  He wore a button up light blue shirt that went well with the grey in his vest, while the darker silver-blue tie matched with the dark lines running through both his vest and pants.

Ed Sheeran

Ed Sheeran went causal for this event, wearing only a plain pair of blue jeans, and a simple black t-shirt. Despite his casual look, Sheeran’s performance was one of the highlights of the evening.

Paul Costabile

Paul Costabile of I Heart Radio looked great in his burgundy jacket, dark pants, and white shirt with black tie. A pair of black tuxedo shoes finished off his outfit. The I Heart Radio website was one of the sponsors of the event, and Costabile chatted with a number of attendees, including Ariana Grande.  The two of them added reindeer antlers to their outfits while posing for a picture. These were just a few of the amazing actors, singers, and other celebrities who appeared at the event.  It’s just the first in a month that will see celebrities showing off their holiday outfits.
