Red Carpet Report Card: 2011 ACM Awards

Taylor Swift
Grade: A

As usual, the country cutie did not disappoint upon arriving at the 2011 Academy of Country Music Awards -- held at the MGM Garden Arena in Las Vegas -- wearing a gorgeous pale yellow Elie Saab Couture gown. Neil Lane jewels and long wavy locks completed her elegant ensemble.

Carrie Underwood
Grade: B+

Carrie Underwood -- who's also know for her impeccable sense of style -- picked a deep purple Jean Fares Couture frock for the occasion. While it didn't necessarily do her fab physique justice, Carrie still looked stunning.

Wynonna and Naomi Judd
Grade: F

On the flip side, mother-daughter duo Wynonna and Naomi Judd -- who aren't exactly known for being fashion plates -- also lived up to their reputations when they arrived wearing these garish getups.

Miranda Lambert
Grade: C

While she's currently one of country music's hottest stars, Miranda Lambert's low-cut, Grecian-style Lorena Sarbu gown was far from white hot. Instead of accentuating her curves, we have a feeling Miranda spent most of the night worrying about how to contain them!

Martina McBride
Grade: B+

Also opting for a Grecian goddess look was Martina McBride, who paired her one-shoulder Pamella Roland creation with an opulent gold belt and shoulder-grazing tassel earrings.

Reba McEntire
Grade: D

Reba McEntire, who co-hosted the show, hit the red carpet in a lackluster copper-colored gown, which perfectly matched her fiery tresses. A gothic cross choker and black cuff topped off her confusing look.

Lady Antebellum
Grade: B+

Hillary Scott flanked by bandmates Charles Kelley and Dave Haywood glammed it up in a gorgeous, beaded Georges Chakra gown and bold bangs.

Chace Crawford
Grade: B

"Gossip Girl" hunk Chace Crawford showed up for the event sporting slick-backed hair and a gray suit, which he dressed down with a casual, gray henley shirt. Think he was cheering on his ex-girlfriend Carrie Underwood?

Julianne Hough
Grade: B+

The pro dancer-turned-country singer strutted her stuff in a sexy coral halter dress. That Ryan Seacrest is one lucky guy, eh

Kristian Bush and Jennifer Nettles
Grade: B-

Sugarland's Kristian Bush stepped out in his signature suit and fedora, while Jennifer Nettles sported a black gown with interesting web detailing. Unfortunately, we couldn't take our eyes off her tacky wing-adorned heart tattoo!

Sara Evans
Grade: B

Sara Evans showed off her gams in a sparkly-yet-rather-casual BCBG Max Azria dress, blazer, and strappy platform sandals.

Darius Rucker
Grade: B

Former Hootie and the Blowfish frontman Darius Rucker opted to pair his crisp white blazer with a purple button-down and matching tie. Salt-and-pepper scruff completed his summery look.

Casey James
Grade: B

Following in Rucker's footsteps was former "American Idol" contestant Casey James, who suited up and even pulled his hair back into a ponytail for the occasion.

Diana DeGarmo
Grade: C-

Another "Idol," Diana DeGarmo, attempted to get all dolled up for the awards show ... in a pink prom bomb.

Luke Bryan
Grade: B-

Luke Bryan took a fashion risk by pairing his black jeans with a funky patterned black blazer. Do you think it was a hit ... or a miss?

Jennette McCurdy
Grade: D

"iCarly star/aspiring country singer Jennette McCurdy may only be 18, but she's certainly old enough to realize that her hideous, rhinestone-adorned Mandalay mini and hot pink peep-toes would garner her attention for all the wrong reasons!

Jake Owen
Grade: B+

While everyone might not agree, Jake Owen scored extra points with us for daring to be different in a dapper burgundy-and-gray pin-striped suit, which he accessorized with cowboy boots and boutonniere.

Laura Bell Bundy
Grade: A-

All eyes were on actress/singer Laura Bell Bundy thanks to her shimmering, embroidered Jean Fares Couture strapless mermaid gown.

Brooklyn Decker
Grade: B+

Model/actress Brooklyn Decker modeled her new, short 'do in a simple -- yet classy -- form-fitting Victoria Beckham frock.

Alabama
Grade: D+

Alabama's Jeff Cook, Teddy Gentry, and Randy Owen have been together since 1969, but they might want to consider updating their look!

Sunny Sweeney
Grade: B-

Aside from her skunk-like locks, Sunny Sweeney played it safe in a navy, strapless number.

Meghan Linsey
Grade: C

Steel Magnolia's Meghan Linsey donned a ruffled Ina Soltani design, which she accessorized with black nails, a sparkling clutch, and a seriously outdated matronly 'do.

Josh Kelley
Grade: C+

Unfortunately, Katherine Heigl's singer/songwriter hubby Josh Kelley ruined his navy suit and checked shirt combo with a wrinkly tie.

Carter's Chord
Grade: B-

Musical sisters Emily, Becky, and Joanna Robertson looked cute in their minis. Too bad they paired their fun frocks with clunky footwear!

Nicole Kidman and Keith Urban
Grade: B+

Despite their drastically different skin hues, Keith Urban and wife Nicole Kidman color-coordinated perfectly for the awards show in dark ensembles. Keith looked comfy in his suit thanks to his open-collar shirt, while Nicole vamped it up in a snakeskin L'Wren Scott frock, fur bolero, and black Manolo Blahniks.
