The network requests that "buttocks and female breasts are adequately covered" for the televised award show. The memo sent out Wednesday also warned against "see-through clothing," exposure of "the genital region" and said that "thong type costumes are problematic."
Representatives for CBS and the Recording Academy declined to comment on Thursday. Deadline Hollywood first reported the memo.
CBS broadcast the infamous 2004 Super Bowl halftime show that included Janet Jackson's "wardrobe malfunction." The network was initially fined by the Federal Communications Commission, though the fine was later overturned.
The 55th annual Grammy Awards will be held Sunday 8 p.m. EST at Los Angeles' Staples Center.
