CBS has issued a stern wardrobe advisory for those attending the Grammy Awards saying that the guests must make sure that their genital regions are "adequately covered," and they should not flaunt their nipples, breasts, buttocks, according to a leaked email.

The requirements, directed mostly at female awards attendees, also include the specific instruction that there should be "no visible 'puffy' bare skin exposed" in the genital region and anyone flouting these rules will risk not appearing on the TV, the Independent reported.

The missive leaked to Deadline said that thong type costumes and showing bare sides or under curvature of the breasts are problematic.

The e-mail said that the guests should avoid baring flesh under curves of the buttocks and buttock crack.

The e-mail added that celebrities should avoid sheer see-through clothing which could possibly expose female breast nipples.
