I think you should have a little chat with your daughter. You should let her know that you know that she dresses inappropriately when she's out of the house. Tell her that you realize there is nothing you can do about this - you're not going to be following her around to make sure she stays dressed! However, remind her that the reason you have your dress code is to protect her. You don't want her provocative appearance to lead to any kind of harm. Tell her that you realize she probably thinks you're ridiculous because, at her age, she can't imagine what you are talking about (teenagers have a sense of invulnerability and naivety) but she should remember that even if she can't follow your logic, you love her more than life itself and you wouldn't waste your time giving her bad advice. So she can take it in the spirit it is offered in, or she can ignore it - she's a free person. Ultimately, her safety and well-being is up to her, not you. The dress code still stands, of course.    Now, if you have a good relationship with this young lady, your words may penetrate her heart. If you are always critical, controlling or unpleasant, however, chances are she won't be impressed. So remember to always work on strengthening the relationship through following the 90-10 Rule (see Raise Your Kids without Raising Your Voice for details).  Sarah Chana
