Did Katy Perry not get the "buttocks and breasts" memo warning stars to be "adequately covered" at the Grammys? It certainly doesn't look like it!

While we didn't love the beading or the color of Perry's mint green Gucci gown, there's no denying that John Mayer is a lucky man. Jennifer Lopez also seemed to flout the dress code, covering the key areas with her leotard gown but also trying to show as much skin as possible. Trying a bit too hard, perhaps?
