Bella Thorne is quite the fashionista.

The 15-year-old Disney star might still be in high school but she certainly held her poise among the grown-ups at Monday's premiere of The Iceman in Los Angeles.

Bella was a charmer as she hit the red carpet in her winning outfit that was a throwback to the 1950s with its black-dotted white sleeveless blouse and shimmering turquoise mini skirt.

Adding to the enchanting illusion was a large and sparkly black bow on top of her flowing mane of coppery hair.

She also wore bright yellow polish on her fingertips, which gave her overall appearance a whimsical feel.

The Shake It Up! star definitely gave this mellow event the jolt it needed as she sprinted down the red carpet in her pointy studded black heels, stopping now and then to pose and make funny faces.

Bella doesn't star in the film, but is obviously a fan of the people that do including Winona Ryder, James Franco and Michael Shannon.

The movie centres on a real-life New York hitman who, in 1986, was convicted of murdering dozens of men for various crime organizations.

The film is rated R for strong violence, language and some sexual content so Bella couldn't even go see it on a regular day without an 18-or-older adult present.

When she's not attending industry events, the young star prefers to spend time with her boyfriend Tristan Klier.

Earlier this month, the two were seen enjoying a trip to a pottery painting shop in Los Angeles.

The multitalented star is currently embarking on her Bella Thorne and Friends Concert Jam 2013 tour which runs through mid-June.

Her duet with Shake It Up! co-star Zendaya Coleman entitled Fashion Is My Kryptonite also earned a Radio Disney Music Awards nomination for Best Music Video.

The Radio Disney Music Awards show is set for Saturday at Nokia Theatre L.A. Live.
