It does not seem to make a difference, clothes, jewelry, make-up, perfume or cigarettes, all have ads that represent them using sex.
Advertisers use beautiful men and women to show their products to the world.
By using perfect rather than mediocre people, advertisers appeal to our need to be accepted, and our dream of perfection. No matter how much we shun the girl that is just too skinny or the guy that is just too built most of would love to look like them. You almost never see a plus size model in an advertisement. Even though there may be an article on larger sized men and women on the opposite page, it is highly unlikely that they will be marketing a product for a company. Reading most of the magazines that are geared toward teenage girls or young women you would assume that it is trendy to be bony and pale.
