Hailee Steinfeld attended Hot 99.5’s Jingle Ball 2015 in Washington, D.C., Monday night in a fashion-forward ensemble.

Hailee Steinfeld’s Latest Look

Steinfield, 19, arrived at the Verizon Center in a cropped dark green jumpsuit from ASOS. The number featured a patent leather block that matched her high black patent leather Stuart Weitzman boots. She brought the look together with her hair styled down and straight and cat-eye makeup.

Steinfeld was styled for the event by stylist Karla Welch. “Feeling #StarWars @HaileeSteinfeld in a mod jumpsuit,” Welch captioned a red carpet shot of the singer and actress.

As Steinfeld revealed in a recent interview, Welch has been working as her stylist for the better part of her career. “I have many style icons. I’ve been working with Karla Welch since I was 13 years old and I have sent her endless references to various people from different eras,” she told W Magazine. “I take from different inspirations like Madonna, Rihanna—just kind of that London street-chic vibe. What’s great is I feel now being a recording artist, I’m able to experiment with my look. I’m still finding it.”

After doing the red carpet and performing onstage at the concert Monday, Steinfeld took to Twitter to thank her adoring fans.

Steinfeld also thanked the sponsors behind the event, who provided her with some much needed sugar before she hit the stage to perform.

Though Steinfeld has been throwing herself into music these days, the True Grit star has also been working on a few acting projects. She’ll next appear in Peter Billingsley‘s Term Life with Jon Favreau, Taraji P. Henson and Vince Vaughn. She also has the third Pitch Perfect movie to shoot in the near future.
