This year, KIIS-FM featured a whole bunch of acts at their annual Jingle Ball, including Justin Bieber and The Wanted. Many of our favorite stars arrived that night ready to rock out to all the amazing acts. Check out our favorite looks from the night below!

Ariana Grande‘s dress shows off her usual girly style with a metallic twist. We love how holiday appropriate this dress is! And can we just say how she looks just as crazy gorgeous (maybe even more) with her newly dyed brown locks? Ariana completes this look with hoop earrings and party-ready gold pumps.

Taylor Swift must have taken a little hint from Ariana for the night! She showed up in this gold and black metallic dress and looked super adorable. Tay sports her classic red lipstick and black high heels to pull this simple yet chic look together.

Vampire Diaries star Kat Graham looks ready to rock in this daring zip-up dress and high ponytail. The simple pattern of gold rings against the white is complemented by some seriously bold jewelry- that’s a statement necklace if we’ve ever seen one!

Kenall Jenner dressed sleek and edgy for Jingle Ball. She pairs a leather pencil skirt with a long-sleeve peekaboo gray bouse. She keeps her accessories simple, but the necklace totally complements the silver embellishments on her ankle boots.
