What I learned from my reading of my last few contemporary romances:
Romance heroines should have big breasts.
But women who use money to get themselves new breasts are trashy creatures who deserve nothing but contempt and ridicule.
Romance heroines should be gorgeous, curvy, and sexy.
But women who refuse to eat for fear of their expanding waistline are described, usually from the hero's point of view, as vain and unattractive narcissists deserving nothing but contempt and ridicule.
Romance heroines should be naturally stunning and gorgeous even when she wakes up at 3am to greet the hero at the door - the hero will, naturally, see her and be stunned by her beauty even in such a situation.
But women who wear make-up are described, usually from the hero's point of view, as trashy, vain, narcissistic, and fake, deserving nothing but contempt and ridicule.
It is moments like this, when realizing the kind of values prevalent in romance novels when it comes to a woman's physical beauty, that I am glad I am not a romance heroine. Who could live up to such ridiculously high standards?
