2013 Grammys Red Carpet

In an emailed Wardrobe Advisory sent by the CBS's Standards and Practices committee, Grammys attendees were cautioned against sheer see-through clothing, "thong type costumes" and "exposing bare fleshy under curves of the buttocks and buttock crack. Bare sides or under curvature of the breasts is also problematic." But some stars, predictably, still pushed the boundaries.

CBS's Standards and Practices committee release an Advisory to all the  Grammys attendees to follow the dress code and warn against "thong type costumes" and "exposing bare flesh under curves of the buttocks and buttock crack. Bare sides or under curvature of the breasts is also problematic." Stars still took the risks.
