Grammy winner Bonnie Raitt is dressed just like the Grammys prefer; no bare curves and no adventurous slits in skirts.

The Grammy Awards will air Sunday on CBS, and the network wants the stars to come fully clothed.  At the very least, CBS is asking the stars to "Please be sure that buttocks and female breasts are adequately covered," according to a memo distributed to attendees this week.  The network also says in the memo that "thong type costumes are problematic."

Apparently the memo is the result of a conference call, and was never meant to be written down and distributed.  The memo also says, "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."

You can't blame the network for being a little jumpy.  It was just last Sunday that CBS accidentally let an f-bomb by Ravens quarterback Joe Flacco make it on the air.  This Sunday, they're trying to tame a group of artists not exactly known for dressing conservatively.

Dress code aside, the Grammys will feature a few performances that may be the talk of water coolers on Monday.  Sting is scheduled to perform with Rihanna and Bruno Mars; and Elton John will perform with fellow Brit, Ed Sheeran.  Something tells us Sting and Elton will have no trouble adhering to the dress code.
