We've talked about the importance of modesty, and we've talked about how to be modest. We haven't yet talked about what to do when someone else is immodest, and that's what we're going to do today. You've probably seen lots of immodest girls in your life. Sadly, we've grown used to short shorts, tight dresses, and low shirts in today's society. They're everywhere, even in the winter (depending on where you live. I live in Texas, so this is a problem due to our warm weather). We've all run across people who dress immodestly, even if it's on accident. How do we approach them about this?
First, you have to be dressed modestly. You can't tell someone that what they're wearing is wrong if you're dressed the same way. That doesn't make any sense at all.
Second, you have to be gentle about it. Most of the time, immodesty stems from a lack of education. The girl probably genuinely does not know it's wrong, usually because her parents haven't taught her about modesty. Making her feel guilty or ashamed is not effective. If she's not a Christian, that could drive her away from Christ. If she is a Christian, she deserves to know the information to help her be a better Christian. In no way should you use harsh words.
Third, offer an alternative, or a solution. Usually, it's not helpful to just tell someone that they're in error, and leave them on their own. Be prepared to help her out. Offer her your sweater if her shirt's too low, or ask if she wants to borrow something of yours. Depending on the situation, you might be able to help or not.
Finally, make sure you have the authority. What do I mean by that? In Titus 2, we're told that older women are supposed to teach the younger women. If you're thirteen years old, do you have the right to tell a thirty-five year old that she's dressed immodestly? No, not really. If you're fifteen., do you have the right to tell a twelve year old that her clothes are too revealing? Yes, you do.
Again, just be careful about how you do it. Tell the truth in love.
