With eight nominations at the Academy of Country Music Awards, Miranda Lambert made sure she was dressed to impress — and she definitely didn't disappoint.

While wearing a floor-length dress with a plunging neckline and high slit, the 31-year-old turned quite a few heads on the red carpet. But even more shocking than her barely-there dress was her slender frame. The country singer seems to have lost a significant amount of weight recently and by the looks of it, she's in the greatest shape of her life!

Take a look:

Miranda ended up winning half of the awards she was nominated for, including Album and Song of the Year, but lost out to Luke Bryan for the biggest award, Entertainer of the Year.

Still, when it comes to fashion, we're considering the 'Automatic' songstress the overall winner of the night!
