Wear clothes that I like without worrying about what other people think

I used to do this all the time in high school and it was so much fun and made me feel so good about myself. It was pretty hit or miss, but even when I kinda looked like a nut, people would just shrug it off, and if I looked good, the compliments would be more meaningful cause I would know I didn’t really look like anyone else at school. Then I came to college and got scared, so I don’t do this any more, but I think if I started again I would be a lot happier.
