21 Stars Under 21 Whose Closets We'd Like to Raid

Pick up any tween magazine, and you'll likely see actress Peyton List gracing the cover. It's no wonder — this 16-year-old has the styling expertise of a seasoned pro. We'll definitely be looking to her for inspiration for day 25 of #stylinghacks, when we have to layer something unexpected.

The always-classy Hailee loves a good feminine look, and judging from this Michael Kors dress she sported back in October, the style really suits her. Coming up next year from this newly 18-year-old? More bound-to-be-amazing outfits from Pitch Perfect 2 premieres!

The baby of the Kardashion/Jenner family isn't really a baby anymore. Kylie's been known to rock some pretty revealing, sexy looks — if not on the red carpet, then on her Instagram. The 17-year-old also put forth her best Angelina Jolie leg on the AMAs red carpet by sporting this stunning, slitted dress.

What were you wearing at 14? Probably nothing as cool and edgy as what Willow Smith wears. How does this teen have such great style at such a young age? We can only imagine it has something to do with her famous, equally-as-fashionable parents, Will Smith and Jada Pinkett Smith.

What do we love most about Chloë's style? The 17-year-old keeps it classy. The actress recently tweeted she wished our fashion would go back to 1928, when "everyone looked so beautiful and appropriate and sexy at the same time."

While Dakota's been on the scene for quite some time, the 20-year-old's recent red carpet looks have definitely wowed us. This fringed red dress by Valentino stole the spotlight at the Effie Gray premiere.

It's no wonder 19-year-old Bethany Mota is one of the most successful YouTube stars ever — she's got the fashionable teen look down pat. Want to steal her style? Just shop her clothing line at Aéropostale.

There's a reason Kendall Jenner is one of this year's top models: clothes just look good on the girl. From very revealing slits to peekaboo dresses to her chill off-duty style, we've started looking to this 19-year-old for fashion inspiration.

You know "Shower" was one of your Summer anthems, but did you know that 17-year-old singer Becky G is supercute? (Probably, if you watched this music video.) Her style kind of reminds us of a mix between Selena Gomez and Ariana Grande, and we're loving this white Nicolas Jebran dress.

Sophie Turner (aka Sansa Stark on Game of Thrones) has a bright, fashionable future ahead of her. Aside from her ability to really rock a pattern, like this Matthew Williamson dress, the 18-year-old was also the star of Karen Millen's Fall 2014 campaign.

Another Game of Thrones star who constantly slays it on the red carpet. Part cool-girl style, part feminine fun, we pretty much want everything this 17-year-old wears.

Trust us: Hailey Baldwin is about this close to really exploding on the fashion seen. With her gorgeous gowns, striking looks, and a crew of It girls (she's friends with Kendall and Kylie Jenner and Gigi Hadid), we're predicting big things for the 18-year-old in 2015.

She may have recently turned 17, but Bella Thorne has been sporting some pretty sexy dresses for years now. While we're not sure our parents would approve, we must say: when you've got it, flaunt it.

We may have been a tad obsessed with Gigi this year, but can you blame us? The new It model (who's only 19) is everywhere, from walking the runways to starring in ad campaigns to hanging out with the Jenner girls — and she's looking stylish while doing it all too.

She's most likely not "A," but Pretty Little Liars star Sasha Pieterse has worn some A+ outfits. The 18-year-old actress looked so classic in this Naeem Khan gown.

This wasn't even a dress that Nicola Peltz was wearing — it was shorts and a floral top from Dior. Only the 19-year-old actress, who frequently sports a cool, cutout look, could pull off something like this.

Who could forget that metallic outfit Zendaya wore to the AMAs? The 18-year-old isn't shy about pulling out all the stops on the red carpet.

Even though Bailee is only 15, we had a hard time choosing which of her recent looks were our favorite — everything she wears is just that good. This LUM dress (which she wore to the Once Upon a Time premiere) ultimately won our hearts, but we can't wait to see everything this young actress wears next year.

This 16-year-old is a style risk taker, that's for sure. Elle's sported everything from crop tops to beaded floral dresses and continues to floor us with her daring fashion choices, like this sporty Creatures of the Wind look.

Quirky? Yes. But there's something about Lorde's style we just love. We wish we could pull off a necktie as well as this 18-year-old can.

Willow's always been cute — how could you not love little Prim from The Hunger Games? — but seeing her in this Christian Siriano gown, she looked all grown up. She's so flawless and fashionable at just 14.
