Best and worst dressed at the 2015 Billboard Music Awards

BEST: Whoa! "Empire's" queen bee Taraji P. Henson turned heads in barely-there dress, which featured a plunging neckline, and revealing cutouts. The sexy gown showed off her fit figure -- but it may have been a little too close to showing off her derriere.  (Photo by Jason Merritt/Getty Images)

BEST: Stunning couple alert! Chrissy Teigen, who is co-hosting tonight's awards with Ludacris, cozied up to her hubby and nominee John Legend. The power couple looked fabulous as usual, but Teigen out-shined her man in a metallic jumpsuit with a daring neckline. (Photo by Kevin Mazur/BMA2015/WireImage)

BEST: White hot! Taylor Swift showed off her fit physique in a daring jumpsuit, which featured major cutouts and a halter neckline. She finished off her sultry style with smoky eyes, sleek locks, and a black clutch. The "1989" singer is definitely taking more chances with her fashion -- and we love it. (Photo by Jason Merritt/Getty Images)

BEST: Nobody can upstage J.Lo! The stunning singer, who recently signed a deal for a Las Vegas residency, showed she'll be the reigning queen of Sin City in a revealing sheer dress with silver sparkles coving up her lady parts. She polished off the look with tousled tresses and smoky eyes.  (Photo by Steve Granitz/WireImage)

BEST: Wowza! "Orange Is the New Black" star Laverne Cox looked better than ever in a white frock with metallic accents and a plunging neckline. (Photo by Eric Jamison/Invision/AP)
BEST: Musicians Patrick Stump, Joe Trohman, Pete Wentz and Andy Hurley of Fall Out Boy were some of the best-dressed gents at the awards show in a series of tuxes and skinny ties. (Photo by Jeff Kravitz/BMA2015/FilmMagic)
BEST: Lookin' good! DJ Calvin Harris showed off his style sense in a slim-fit navy suit. (Photo by Steve Granitz/WireImage)
BEST: Singer Tori Kelly hit the perfect balance between flirty, fun and sexy at the BBMAs in a fringed white frock. She amped up the fun style with big hair and metallic accents. (Photo by Jason Merritt/Getty Images)
BEST: "Empire" star Bryshere Y. Gray looked slick in a snakeskin print gray suit. (Photo by Jason Merritt/Getty Images)
BEST: Kendall Jenner opted for a demure and fashion-forward ensemble with an oversized blazer and skinny jeans. It's a refreshing look for Jenner, who typically gravitates toward more daring getups.  (Photo by Larry Busacca/BMA2015/Getty Images for dcp)
WORST: Kylie Jenner showed off her famous fashion sense in a futuristic striped dress with lace-up booties. She finished off the look with a bold gold belt. But we were a bit bored with the seemingly predictable look from the style maven. (Photo by Jason Merritt/Getty Images)
WORST: We're normally impressed with Hailee Steinfeld's fashion sense, but this ill-fitting frock and sock look is not one of our favorites. What do you think? (Photo by Jason Merritt/Getty Images)
WORST: Little Big Town singer Karen Fairchild showed off her wild side in a black leather dress and over-the-knee heels. We can't say we're in love with the daring style. (Photo by Jason Merritt/Getty Images)
WORST: Fifth Harmony's leading ladies -- Lauren Jauregui, Ally Brooke, Normani Hamilton, Dinah-Jane Hansen and Camila Cabello -- hit the red carpet in some fairly interesting white, gold and and black frocks. The matchy-matchy looks and strange embellishments didn't seem age appropriate. (Photo by Eric Jamison/Invision/AP)
WORST: Singer Dencia wore all the colors of the rainbow in this statement-making bodysuit that has us scratching our heads. The different colored shoes she wore also didn't do her any favors. (Photo by Eric Jamison/Invision/AP)

WORST: Singer Rita Ora strutted her stuff in a very revealing white gown complete with gold embellishments and a hot red lip. But the loose-fitting number was way too close to a wardrobe malfunction for our taste. (Photo by Eric Jamison/Invision/AP)

WORST: Iggy Azalea definitely took a fashion risk with her powder blue crop top and skirt combo, which had a sheer side panel. Unfortunately, we're a little underwhelmed by the look. We do, however, like the "Booty" singer's dip-dyed pink tresses, which matched her footwear. (Photo by Jason Merritt/Getty Images)

WORST: Is David Lee Roth a new brand ambassador for Under Armour? The Van Halen hunk hit the red carpet in a bizarre plaid suit paired with a fitness top, sunglasses, a newsboy hat, and athletic shoes. We're officially confused. (Photo by Jason Merritt/Getty Images)

WORST: Tracee Ellis Ross was all smiles on the red carpet, but her leather jumpsuit was subpar at best. (Eric Jamison/Invision/AP)
WORST: Miss America 2015 Kira Kazantsev didn't exactly wow us with her futuristic nude and yellow dress and sky-high platform shows. Her frock seemed to overpower her tiny figure. (Photo by Jason Merritt/Getty Images)
WORST: Estelle showed off her fit bod in a lacy gown with a plunging neckline and sheer panels -- but we gotta wonder what her hands are covering. Too much sheer?  (Photo by Eric Jamison/Invision/AP)
WORST: Actress Stefanie Scott was inspired by the carpet tonight (literally)! She opted for a high-waisted, flared set of bright red pants with a floral crop top -- but we were left wanting a little more. (Photo by Eric Jamison/Invision/AP)

Naturally, the fashion stakes were high, with stars like Jennifer Lopez, Taylor Swift, and Mariah Carey setting the tone – but even newer stars made sure to make a statement with daring and stylish ensembles.

"Empire" star Taraji P. Henson turned heads in a barely-there black gown, while "Orange Is the New Black" actress Laverne Cox blew us away in a flattering white frock with a plunging neckline.

Taylor Swift and Sam Smith Dominate 2015 Billboard Music Awards Nominations

While some celebs wowed in show-stopping outfits, others took fashion risks that didn't quite pay off. David Lee Roth looked like Under Armour's new brand ambassador in a bizarre plaid suit topped off with sunglasses, a newsboy hat and athletic shoes while Iggy Azalea's pale blue two-piece combo nearly put us to sleep.
