Why Kacey Musgraves Had to Perform Commando at the CMA Awards 2014

— -- The dress Kacey Musgrave wore to perform on Thursday night at the CMA Awards had sheer sides, which didn't allow for traditional underwear.

However, at the last minute, the stick-on kind she was using "totally came off," and she had to act quickly.

"So, they were stuck on, and then they weren't stuck on," she told ABC News backstage. "And the curtain was about to come up, so literally I had to rip 'em off and throw 'em to the side."

Musgraves, 26, performed "You're Lookin' at Country," with singing legend Loretta Lynn. However, the singer, who picked up Song of the Year honors for her hit, "Follow Your Arrow," never recovered her lost lingerie.

"They're somewhere around here," she mused. "So, in case you see 'em, they're mine!"
