American Music Awards 2017 Best Dressed

Black-ish star and red carpet pro Tracee Ellis Ross set the tone for the night in burgundy Stella McCartney.

Nothing odd about this Stranger Things' star's look, which is just plum smart.

Fringy and free, This Is Us star Chrissy Metz channeled her inner flapper girl with a frock invoking jazz era fun.

If there's anyone who can get away with a paint splattered get-up it's a teen star, and Caleb makes this quirky look work well.

Timeless, chic and a little bit rock and roll, Big Little Lies' Nicole Kidman looks dressed to kill.

Solid, but safe and slightly sad. Where's the funeral Justin?

Quite possibly the night's best dressed, Jenna Dewan-Tatum slayed in Julien Macdonald.

Never mind that Justin looks dressed for fall while his hubby, Modern Family star Jesse Tyler Ferguson, shines in bright in spring tones--they look great for whatever season they want to believe it is.

She's wearing Coach, but Selena is a first-class knockout in a black leather shirtdress.

Demi is giving a little of a Morticia Adams vibe in this Ester Abner gown, but she's elegant and edgy.

Can Heidi do any wrong?

Riverdale's Archie looks slick and suave in his inventive tux, although we wish he'd play up those standout crimson locks.

Sure, it was probably 200 degrees in L.A. that day, but Sabrina Carpenter's adorable and airy Missoni cloak dress and sky-high Casadei boots respect the fact that it's technically fall -- and freezing indoors. Well played.

This is what off the wall done right looks like! The 15-year-old Stranger Things star shines in a sheath adorned with a chain overlay.

Business Barbie up top, party Barbie below? Girl, no.

There's a lot going on here -- Pockets! A train! A white sad emoji across the boobs! -- but Keltie isn't a total dumpster fire. Not a win, mind you, but not a disaster. So that's something.

Corinne Foxx and her proud papa Jamie kept the lavender and blue trend going strong with her jumpsuit, and his sharply tailored look -- both right for the informal and upbeat occasion.

Slinky and sexy in vivacious red, Laura is packing heat here.

This dress is unfortunately not as goregous as Kelly herself. Her gorgeous hair and makeup are competing too strongly against this distressed sequined gown -- an oddly proportioned situation that looks like it lost a fight with a weed whacker.

Smoking in a Christian Siriano reminiscent of a desert sunset.

"When Safety Scissors Attack," coming soon to a theater near you.

Are you O.K. Nick? Sending thoughts and prayers.

Pared down and serene in J. Mendel, Lea Michele is the definition of glam goddess.

Nothing about Kathryn Hahn's tangerine dress is off per se but a statement necklace or a messy up-do could've turned this good look into a great one.

Royally sharp in his purple Paul Smith suit and blue Christian Louboutins, American Horror Story: Cult star Billy Eichner enjoyed playing with color on the red carpet.

Grown-ish star Yara Shahidi, wearing Prada, likes to take risks with her clothes, eschewing "sexy" for thoughtful looks that say she doesn't follow trends. That said, if we could just send that zebra collar back to the wild, this would be a 10.

Somber, but sexy.

Simple and sexy in Varvatos, Nick Jonas followed a very basic style rule: don't try too hard. And it's a win.

Rocking leather and lace like a BOSS, Maia Mitchell nailed rock star glam for the night.

Ethereal in her gold flaked gown, Camila Mendes looks stunning...even if this is more suited for May than November.
