“Why do we let them dress like that?”

All of which brings me to a question: Why do so many of us not only permit our teenage daughters to dress like this—like prostitutes, if we’re being honest with ourselves—but pay for them to do it with our AmEx cards?

I posed this question to a friend whose teenage daughter goes to an all-girls private school in New York. “It isn’t that different from when we were kids,” she said. “The girls in the sexy clothes are the fast girls. They’ll have Facebook pictures of themselves opening a bottle of Champagne, like Paris Hilton. And sometimes the moms and dads are out there contributing to it, shopping with them, throwing them parties at clubs. It’s almost like they’re saying, ‘Look how hot my daughter is.'” But why? “I think it’s a bonding thing,” she said. “It starts with the mommy-daughter manicure and goes on from there.”

I have a different theory. It has to do with how conflicted my own generation of women is about our own past, when many of us behaved in ways that we now regret. A woman I know, with two mature daughters, said, “If I could do it again, I wouldn’t even have slept with my own husband before marriage. Sex is the most powerful thing there is, and our generation, what did we know?”
