batHH – there is nothing wrong with caring about what others think. That is the way Hashem made us, and it is normal and probably a good thing to some extent. I think that it is healthy to realize that others’ opinions matter to you, and I did not mean to mean to imply otherwise, and I’m really sorry if I made it sound like it’s bad that you care what other people think.
The whole idea of dressing a certain way (no matter how someone dresses) is based on caring what others think, since the way you dress is the way you present yourself to the world.
My point was that if you are comfortable with your manner of dress and the message you are projecting is the one you want to project, and dressing otherwise would not be YOU and would be projecting yourself as something that you are not and you are just feeling peer pressure to change, then you should stay the way you are because I think you will be happier that way.
It’s hard to explain the difference (especially since I don’t know if there always is a clear-cut difference), but I hope you understand what I mean.
