Taking beauty too far??Breast Contouring and Highlighting

Kim Kardashian is one of the famous people who made face contouring very popular but now the trend seems to be edging towards other parts especially the neck and the boobs..

I mean there are even videos on youtube now on how to contour your breasts with makeup! 

So I guess we would be seeing alot of contoured cleavages now..What do you guys think is this a good development or not?? would you consider contouring your cleavage??
