Hey man,
I think you are getting way too caught up in stereo types and belonging to a certain "group" or "style".
It probably sounds like lame advice but just be you.
STOP CARING ABOUT WHAT OTHER PEOPLE THINK
Here is the big thing you need to understand, most people don't care.
Seriously!
You care about the way you look because it's YOU.
Most people are too busy worried about how they look, how their hair is, how their dress is etc. to even notice what's going on with you.
It sounds like you think that you need to be accepted.
What you really need to do is accept yourself and then like it.
Instead of focusing on all of the things you don't like focus on what you do like about yourself.
The thing about fasion is that is changes all the time.
Sometimes I wear a shirt and jeans, sometimes I suite up, sometimes I wear a tie, sometimes I wear a crazy hat and jacket.
It changes all the time, go to the shop and buy clothes that YOU like and that YOU want to wear and then you will develop a natural style.
Also look into imporoving your self esteem, your self confidence and your self worth.
Good luck
Tristan
