Saw this headline on FoxNews.com the other day: "How to get your teenage daughter to wear what YOU want".
Here's I how I do it. I buy the clothes. She wears them. If she wants something I find immodest or distasteful, I don't buy it.
This method works.
Really, parents: there should be no argument over this. You hold the purse strings. If you don't want your daughter to wear crap, don't buy it.
Now, that doesn't mean she has to look like she's one of the von Trapp kids either - with a "modest" dress made from leftover curtains. There are plenty of ways to be fashionable, fun and in good taste.
But stop arguing. You're the parent.
