You mean these advertisements that K.Moss did in the very beginning of the 90s? Her advertisements were "scandalous" because of her thinness said to be creating anorexia amongst the youth and because of her child-like presence. The last three posted are from the most infamous campaign, for Calvin Klein's perfume Obsession. Critics said these were against women's rights and pro-violence, since Moss looked hurt in them and was touching her lip as if she'd been beaten. She was also fully naked and looked sullen.
There are a lot of these advertisements, these are only couple posted.
