The Grammy dress code memo that was leaked last week forbade the award show attendees, particularly the women, from showing too much skin – not everybody decided to listen.

Jennifer Lopez and Kelly Rowland were probably the most scandalously dressed at the 55th Grammys. Lopez, while covering up on top, revealed the full length of her leg in an asymmetrical black dress by Anthony Vaccarello. Rowland wore a full-length Georges Chakra dress of a black and sheer material, which was strategically placed to show everything but the curves CBS forbid, but kind of did anyway.

When Lopez went up to present an award during the night she joked, "As you can see, I read the memo." To which her co-presenter Pitbull replied, "You look gorgeous, you look beautiful, and you inspired the memo."

Other artists were slightly less obvious in their disregard for modesty. Katy Perry wore a tightly fitting long-sleeved mint-green gown that while putting her cleavage front and center, kept with the rules by not showing any sideboob. Country singer Carrie Underwood managed to make quite a spectacle without exposing hardly any skin. Instead the Grammy winner donned a gown of ample fabric, and used it as a projection screen for her performance of “Blown Away.”
