The world grew to know JoJo Siwa and her very particular style — bright colors always topped with a bow! — when she got her start on "Dance Moms" and became a successful YouTuber.

Join Wonderwall.com as we press fast-forward to see her serious style transformation, plus more child stars who dress a whole lot differently today…

Who's that girl? You might be surprised to discover that some of your favorite fashionistas were once child stars who rocked red carpet looks straight from the kids' department. She only goes by one name these days, but back in 2010, young Zendaya Coleman would often hit the red carpet in funky mismatched looks like this one — a flannel over layered tank tops, denim shorts, tights and boots.

Today, Zendaya is arguably the best dressed woman in Hollywood. The "Euphoria" star, who works with celebrity stylist Law Roach, continuously serves up unforgettable red carpet looks — like this custom emerald green Vera Wang gown with a semi-sheer corset bodice and a hip-high slit that she paired with matching Brian Atwood heels at the 2019 Primetime Emmys.

Recognize this majorly dressed-down teen? Scarlett Johansson was a child actress before becoming an A-lister. Though she looks pretty casual here at a 1998 event in Los Angeles, she would grow up to thrive in the high fashion world…
_
This pint-sized cutie rocking teacup-covered overalls, a bright pink T-shirt and loafers on the red carpet in 2002 grew up to be one of our favorite people to watch in the fashion department… Elle Fanning!
_
Elle Fanning consistently wows when it comes to choosing eye-catching fashion. From feminine florals to this edgy gold chain crop top and column skirt combo by Balmain she wore to the 2021 InStyle Awards, this starlet never fails to surprise us with her constantly evolving style.
_
The now super-stylish star of "Grown-ish," Yara Shahidi, scored her first film role way back in 2009 in "Imagine That." When it came time to attend the movie's premiere, she picked this sweet little sleeveless green dress.
_
Years later, and she's still rocking green! Though Yara Shahidi traded her her kiddie couture for haute! The now best dressed beauty wore this glamorous Dior Haute Couture off-the-shoulder frock at the 2021 Primetime Emmy Awards.
_
Look how little she was! Chloe Grace Moretz scored her first acting gig in a big-budget film with 2005's "The Amityville Horror." She's seen here at the premiere in an adorable dress featuring a bright pink sash tied in a bow.
_
We love this evolution! Chloe Grace Moretz has proudly established her own sense of style as she's matured. In recent years, we've seen the actress shift toward more androgynous silhouettes — take, for example, this Louis Vuitton ensemble (just look at that shimmery coat!) she wore to the 2022 Met Gala.
_
As a teen, Lindsay Lohan opted for trendy looks like this 2001 ensemble — a black tank top, camouflage pants and black flip flops to match her chunky choker. These days, the star likes her outfits a little more sparkly…
_
Lindsay Lohan, who stepped out of the public eye for years, developed an affinity for all things shimmery and feminine — like this spaghetti-strap minidress complete with ruffles and feathers, paired with some strappy and sparkly sandals, that she wore to a horse race in Australia in 2019.

Sophie Turner struck gold when she landed a role on HBO's epic fantasy series "Game of Thrones" in 2011. The Northampton, England, native was incredibly on-trend with her little black dress, tights and mesh long-sleeved top, which she paired with red pumps and a red clutch, at an event for the show in 2012.
_
Ten years later, Sophie Turner had really come into her own, maturing in the fashion department by trading trends for interesting designer pieces. She's seen here at the 2022 Vanity Fair Oscar Party in a custom red Louis Vuitton gown while pregnant with her second child.
_
Miley Cyrus rose to fame as the lead on the Disney Channel's "Hannah Montana" and in real life tended to wear more buttoned-up clothing, like she did at an event for TV critics in 2006. My, how that changed!
_
At a Tom Ford fashion show in 2020, Miley Cyrus rocked a black jumpsuit with a plunging halter-style neckline. This is a more covered-up example, as she's certainly been known to wear some racy and edgy ensembles over the years.
_
We fell in love with Hilary Duff in the early '00s when she starred on "Lizzie McGuire." Back in those days, the actress had some funky style — just take a look at this fur-trimmed purple coat she paired with a sheer sequin-embellished top, low-rise jeans, a chain belt and boots in 2002.
_
She's come a long way! Hilary Duff showed off her grown up fashion sense — she's still opting for pretty hues, just with a more glamorous twist — in this crimson Osman gown at the Baby2Baby Gala in 2021. The beautiful long-sleeved, shimmery dress with a thigh-high slit is a great example of her new, sleek style.
_
In 2007 — the same year her hit show "Wizards of Waverly Place" debuted on the Disney Channel — Selena Gomez attended the premiere of "Pirates of the Caribbean" (pictured). Like many kids her age at the time, Sel gravitated toward looks influenced by the pop punk music scene — like side-swept hair and layered clothing.
_
Look at her now! Selena Gomez has since traded in her skinny jeans for seriously flattering designer silhouettes. At the 2022 Critics Choice Awards, for example, she walked the red carpet in a custom Louis Vuitton silk gown with a sleek halter neckline and gorgeous keyhole detail on the bodice.
_
This little one in a bright purple dress and tiny heels would grow up to be on one of the most stylish shows of all time — the reboot of "Gossip Girl"! Emily Alyn Lind, seen here in 2011, now dresses as fabulously as her Upper East Side character.
_
Emily Alyn Lind, who stars on the HBO Max reboot of the fashion-obsessed "Gossip Girl," showed off her own unique style sensibility in this furry white halter minidress by Saint Laurent in 2021. She paired the funky frock with black tights and open-toed black pumps then added a bit of sparkle via a jewel-embellished chain belt.
_
A very young Emma Roberts rocked a casual graphic tank top and camouflage trousers with loafers to a movie premiere in 2000. These days, she is always perfectly polished on the red carpet…
_
These days, you could describe Emma Roberts' fashion sense as classically glam. Her 2020 Vanity Fair Oscar Party look — a sleek strapless Alexandre Vauthier gown — is a great representation of her typical style on the red carpet now.

We first met Abigail Breslin as a child actress when she made her film debut in "Signs" in 2002. She's seen here at the premiere in this pretty little dress and Mary Janes carrying a pink stuffed puppy. Nowadays, she still has a penchant for pink…
_
Abigail Breslin showed off her grown-up take on pink at the Academy Museum of Motion Pictures Opening Gala in 2021, rocking this stunning Pamella Roland design complete with an elegant cape detail.

A young Joey King showed off her cool style at a young age — check her out here at the "Despicable Me" premiere in 2010 in a striped Rolling Stones T-shirt dress and matching Converse sneakers. Fast-forward to today and she has the same slight edge but with a little more polish…
_
Now that Joey King is all grown up, she opts for cool coordinates like this rich blue quilted set from Milkwhite. She wore this three-piece look to the premiere of "Moonfall" in 2022.
_
Ever since we met her when she starred in the first installment of the "Harry Potter" movie franchise, Emma Watson has showed off an eccentric fashion sense off screen. Just check her out at the "Harry Potter and The Sorcerer's Stone" premiere way back in 2011 in three different shades of green in one outfit.
_
Though she continues to mix things up in the fashion department, Emma Watson does so in a dressier way these days. Take her 2021 Earthshot Prize Awards ensemble, for example: a Harris Reed creation in black and white that was part elegant ballgown and part wide-legged pantsuit.
_
Growing up as a little girl in the limelight, "Mad Men" star Kiernan Shipka showed off her early affinity for fashion, especially darling gowns — like this beautiful, shimmery blue dress she wore to the 2010 Screen Actors Guild Awards — whenever she attended a grown-up red carpet event.
_
She still loves nice dresses! As she's grown older, Kiernan Shipka has edged up her sense of style, which she demonstrated when she attended the 2022 Vanity Fair Oscar Party in a sexy black lace frock from Elie Saab featured a daring neckline and cut-outs along the waist.
