Bella Thorne channeled a sophisticated look at the 2015 ELLE Women In Music celebration presented by eBay, held at Boulevard3 on Wednesday night in Hollywood.

She wore a patterned dress by Donna Karan from her Spring 2015 Ready-to-Wear collection, it looked like a top and skirt at first glance, but the faux cropped top was actually a cut-out.

The print and the color of the dress made it look formal and mature but the mid-length, neckline and cut-out put a youthful and fun vibe to it.

Bella topped off the look with a pair of contrasting, strappy heels from Nicholas Kirkwood and accessorized with an Edie Parker clutch, Bauble Bar earrings and multiple rings from Jacquie Aiche and EF Collection.

The Disney Channel princess let her strawberry-red hair down effortlessly and blow-dried to perfection. Her makeup was flawless and she shared to her fans through Instagram a snap of her look for the event.

"What a difference a day makes," she captioned.

The 17-year-old actress joined Victoria Justice and Debby Ryan inside the annual event, where they got to see Alanis Morissette and Tinashe perform.

Victoria wore a Sanyae Demure white minidress, Stuart Weitzman blue heels, Edie Parker rectangular clutch and Henri Bendel jewelry.

While Debby wore Lublu long dress, Rodo clutch, and Pamela Love jewelry.

The three former child stars cosied up and was seen enjoying the night and each other's company.

Bella took a break from her very busy schedule to go to the shindig. She has just completed filming two movies, the horror film 'Amityville: The Reawakening' and drama thriller 'Big Sky.'

She is also currently filming the fourth installment of 20th Century Fox box office hit, Alvin and the Chipmunks. She will play the character Ashley and the it will be released on December 23.
