Celebs at the 2013 Grammy Awards: What rules?

Feb 10, 2013 at 9:25 p.m. ET

The red carpet at the 2013 Grammy Awards was more subdued than in other years, maybe thanks to the new rules issued by officials. Still, a few celebrities managed to buck the trend.

Katy Perry at the GrammysThe suits behind the Grammy Awards had specific instructions for all the celebs attending the 2013 show: No T&A.

"Please be sure that buttocks and female breasts are adequately covered," read the official advisory. "Please avoid exposing bare fleshy under curves of the buttocks and buttock crack. Bare sides or under curvature of the breasts is also problematic. Please avoid sheer see-through clothing that could possibly expose female breast nipples. Please be sure the genital region is adequately covered so that there is no visible 'puffy' bare skin exposure."

And surprisingly, most celebrities followed the rules, save for a few notable exceptions.

"They didn't say anything about leg!" Jennifer Lopez told E! News as she showed off a lot of leg in her Anthony Vaccarello dress. "I thought I was being such a good girl! A little shoulder, a little leg."

Miranda Lambert also showed off the "fleshy" parts of her breasts.

"The thing they sent out to all the stylists and stuff was like, 'Don't show your side boob and puffy skin...,'" she told E! News. "It was like, 'What is that?'"

Katy Perry also took the opportunity to show off the, er, fleshier parts of her incredible body. However, Kat Von D summed it up nicely when asked about adhering to the red carpet rules.

"We don't care about guidelines," she told Giuliana Rancic.
