I believe that there is light at the end of the tunnel. We can stand up for what we know is right. We can dress in a way that shows that we respect ourselves. It is easy to dress immodestly and follow the crowd, but not everyone has the strength to stand out and be an "example of the believers" (1 Timothy 4:12). We can.
A friend of mine wrote an amazing post about modesty a few months ago. I highly recommend you read it. It was inspiring and it really made me think.
In the LDS "For the Strength of Youth" pamphlet, it gives very good counsel on modesty. I believe that we all, no matter what our age, should follow the counsel in this amazing pamphlet. The following quote is from it.
"Prophets of God have continually counseled His children to dress modestly. When you are well groomed and modestly dressed, you invite the companionship of the Spirit and you can be a good influence on others. Your dress and grooming influence the way you and others act.
Never lower your standards of dress. Do not use a special occasion as an excuse to be immodest. When you dress immodestly, you send a message that is contrary to your identity as a son or daughter of God. You also send the message that you are using your body to get attention and approval.
Immodest clothing is any clothing that is tight, sheer, or revealing in any other manner. Young women should avoid short shorts and short skirts, shirts that do not cover the stomach, and clothing that does not cover the shoulders or is low-cut in the front or the back. Young men should also maintain modesty in their appearance. Young men and young women should be neat and clean and avoid being extreme or inappropriately casual in clothing, hairstyle, and behavior. They should choose appropriately modest apparel when participating in sports. The fashions of the world will change, but the Lord’s standards will not change."
The fashions in the world change, but the Lord's standards don't. I believe that. Let us stand together and be an example of the believers!
