Convergence and beauty.

Dove's campaign for breaking down the impossible standards expected of women today is a very good thing.
Diversity is what makes us human, and all of us as individuals should present a different image. Emulating a magazine or billboard doesn't make a woman more beautiful, it makes her less attractive and less diverse.
Think about it, if everyone achieved their ideal beauty from a magazine and presented it perfectly, the idea and concept of beauty would be lost.
I'm sure everyone has a different concept of beauty of course. That in itself should be already tearing down the impossible bars women set for themselves. We even have different words describing attractiveness: cute, lovely, beautiful, sexy, hot, attractive. These all have slightly different connotations depending on how we use them. The English language itself proves that we all have differing concepts as a whole, and therefore shouldn't have converging concepts of beauty settled on one or two images. We'd lose a little bit of diversity, something we should be celebrating as a whole.

I feel it should be said that not all women feel that they need to fit this mold. The same way I don't feel I need to be muscle bound and lifting weights to be awesome, I'm pretty sure most girls don't feel like they need to be 6 foot tall sticks in heels to feel attractive.  Yet this ad campaign gives the ones that do feel the need to emulate models a well needed kick in the pants and a compliment to boot.
