The Best & Worst Dressed Stars at the 2016 Billboard Awards

Zendaya won a spot among the best-dressed of the night, and looked gorgeous in a peach-colored bra and skirt ensemble by Calvin Klein Collection. Sporting simple straight hair and minimal makeup, the actress proved she could pull off a more understated look just as flawlessly as her usually bolder outfit choices.

It was black, white, and wrong all over. The "New Americana" singer's Fausto Puglisi dress had way too much going on for the magenta carpet.

Leave it to the Love & Friendship star to steal the show from the musicians. The ageless actress stunned in an ivory Hamel gown that featured edgy sleeves, bringing on the glamour.

The "Dangerous Woman" singer couldn't quite pull off her futuristic-looking Atelier Versace halter gown.

The best body in the business! The "Body Party" singer was perfection in a slinky silver Philipp Plein dress. The event's host went on to slay in seven different outfits throughout the night.

The "Cool for the Summer" singer's tweed Chanel blazer and wide-legged trousers seemed to age her, not to mention resembled an '80s costume.

The Bad Moms actress hit it out of the park in a strapless Zuhair Murad couture minidress, and her simple updo was a perfect match.

The Orange Is the New Black actress's plunging Michael Costello dress was perfectly fitted and managed to be sexy without being over-the-top.

The champion skier's blue Luciana Balderrama dress looked a wee bit too small.

Work it ladies! The girl group looked super-chic on the red carpet, and made a dramatic entrance thanks to their gothic-style looks.

The Empire star has killer abs, but these high-waist leather trousers are a definite no.

The "Motivation" singer was a goddess in a shimmery Labourjoisie gown, and was fashion-forward in a slicked-back 'do.

The violinist's nude mermaid gown's exposed tulle was a little sloppy on the magenta carpet.
