For me it depends on WHY you are showing off all (or most) of your body. A lot of girls dress in revealing clothes because they are insecure and feel like they need to show everything to get a guy to noticed or like them. To me that isn't okay, but if they're wearing clothes that look good, because they love their bodies... Props to them! It isn't our place to tell girls what to or not to wear. Is it a girls fault if a guy's eyes and minds wander? No, they can't be blamed for that completely. Parents should teach their sons better.
So many people make it out that a girls body is an "evil" thing. To be covered up and hidden. They aren't, they are beautiful, wonderful, and amazing things that God gave us. I personally don't want every guy looking at my boobs or legs, so I'll save that for those particular people I want to see. To each their own. Should we walk around naked? No, but it shouldn't be up to other people what we do or don't wear.
11 Brothers and sisters, do not slander one another. Anyone who speaks against a brother or sister or judges them speaks against the law and judges it. When you judge the law, you are not keeping it, but sitting in judgment on it.
12 There is only one Lawgiver and Judge, the one who is able to save and destroy. But you - who are you to judge your neighbor?
- James 4:11 - 12
