Announcing the 20 Most Stylish Celebrities of 2017

Not just a breakout for her acting chops on Netflix's Stranger Things, Millie Bobby Brown has had a defining red carpet year — all by the age of 13. Capped off by Calvin Klein's appropriately demure tea-length dress at this year's Emmy Awards, the star's style is playful, daring, and, much like her roles, wise beyond its years.

The best part of news that Yara Shahidi landed a spinoff to ABC's Black-ish is the promise of more style moments to look forward to in the coming year. Smart not only refers to her intellect (she didn't get into Harvard for nothing), it applies to her personal style too, which ranged from pretty, sparkly gowns to thoughtful graphic tees.

From the highs to the lows, what a year Selena Gomez has had. While she's always an inspiration for her candidness, she blew us away this year with an understated style evolution that saw her in more relaxed silhouettes and retro cuts worthy of a fashion fetish.

Kaia Gerber didn't just burst onto the runway this year, she also made quite the impact off of it too. It's no shock that this genetically blessed model could nail catwalk-worthy looks, but her street style's where she both brought us back to the days of Cindy Crawford and led the way for a new generation of model-off-duty dressing.

This might go down as the year of the suit, and so too Evan Rachel Wood as its reigning queen. With a vow to forgo gowns on this year's red carpets, the Westworld star made both a fashion statement and a statement.

It's almost cheating when you look this good in everything you wear, still Priyanka Chopra officially dominated Hollywood with her bold and fearless red carpet picks. Not only did she look gorgeous in her glamorous gowns, but she also had fun while doing it.

Meghan Markle had some big shoes to fill as Prince Harry's plus one, and whether it was on the cover of Vanity Fair or on more casual outings, she did just that. Recently, when she appeared at the Invictus Games in a $185 Aritzia dress, it was clear we have the next Kate Middleton on our hands.

Rihanna's biggest contribution might have been to the makeup world this year, still her fashion game remains on point. Entirely unapologetic, this style icon takes risks, and that is always a thing of beauty.

This one came out of the blue like an iceberg in the Atlantic (we couldn't resist). With a little help from superstylist Law Roach, Celine Dion had her arguably best and definitely most stylish year, whether it was strutting on Instagram or stepping out on the streets of Paris. Much like the singer herself, her look is sultry and quirky in a way that makes our hearts go on and on.

When Alexander Wang calls you the "body of our generation," people take note. Dressed in the designer's Met Gala jumpsuit, this catwalk queen proved the designer's point right.

Not to be outdone, Gigi had a pretty stellar year too — from an ongoing collaboration with the hotter-than-ever designer Tommy Hilfiger to magazine covers galore. Whether she was dressed up, dressed down, or even borrowing from the boys, one thing was for sure: she looked good doing it.

All hail! Nicole Kidman's big year extended from the silver to the small screen and straight onto the red carpet. We've always loved the elegant star's fashion-forward picks, and this year she proved she's only getting better!

Elle Fanning must have been taking some notes on the set of The Beguiled, because this was one seriously stylish red carpet circuit. Wearing age-appropriate yet sophisticated designs, this young star promises to remain on the best dressed list for years to come.

Never one to play it safe, this fashion royalty took her own place on the throne this year. Mixing bold prints, bright color palettes, and sparkle, the playful dresser makes fashion fun.

Just when we thought Amal Clooney's style couldn't get better, presenting: Amal Clooney's maternity style. The polished dresser looks ready to get down to work no matter what the occasion — whether it's a gala or the courtroom.

This was the year that we fell for another royal, Princess Deena Aljuhani Abdulaziz of Saudi Arabia. A bona-fide street style star, this glamorous dresser earned a brief stint as the editor in chief of Vogue Arabia for its recent launch and continues to turn heads with her modest yet opulent Fashion Week looks.

Proof that sexy doesn't have a size, Ashley Graham won the hearts of fans and designers alike with her curve-hugging dresses and skin-baring styles. Bathing suits? Yes. Minis? Yes. There was nothing Graham couldn't wear — or do — this year.

Pardon the pun, but this American Horror Story actress quite simply kills it every time. Willing to take risks and step outside of the box, much like her acting choices, this fashion-forward star had some of the year's most unexpected and winning red carpet looks.

We've always had a bit of a style crush on this edgy dresser, but this was truly her year with a major red carpet campaign for Big Little Lies that was capped off with a Dior design as colorful and exciting as she is at the Emmys.

Nobody has done more for swimsuit fashion this year than the queen of Instagram bikinis. Still, this beauty doesn't need to be wearing beachwear to heat up our screens.
