Now you may be getting the point... photographers and models are chosen to convey specific stereotypical looks for different fashion products. The goal in the end product (advertising) is to get the viewer to identify with the woman in the photo and want to be more like that...
And then run out and buy jeans, jewelry or whatever they happen to be selling.
Often they will throw in a semi-shaved ruggedly good looking male model in a clear effort to say... "Buy this and you will get a handsome man!"
And it works very easily because people are basically stupid and fall for it even when they know they're being pitched advertising.
