Cleavage has become a major fashion staple on family television. The types of shows like NBC's The Voice and America's Got Talent have millions of viewers each week.
The "need" to bare cleavage on these family shows is distasteful not appropriate. Because these shows are in fact family oriented, means that the clothing choices of the celebrities should reflect exactly that...family.
Let's keep "sex" and "sexiness" out of family television shows and set some respectable clothing guidelines.
