Like most of the pictures in womens' magazines :-). I've wondered about this, because I would like to say just that there's something nice in women affirming that women can be really beautiful. Too bad it is a very particular look and beautiful means sexy. It's still enough to spark a trail of thinking about being desirable, which in and of itself is quite strong.
Of course, it might be more useful to affirm women are *already* beautiful. I don't think any woman looks at photos like these and feels an intense affirmation of her beauty in the present moment. It's much more, shall we say, anticipation.
