I'd have to say, when I think back to it my style has varied so much over a short period of time. In beginning of High School, I was a casual dresser presenting as female. Wearing bagging shirts, character shirts, things of that nature. Never any sort of fixed up or nice. After I started to learn about myself, when I realized I didn't have friends, and got into my super depressed stages and hating the world I went toward the goth style. I stayed that way for a few years before I finally opened up my range, started to venture into the "skater" style. Skinny jeans fit better, and look better on me. I like hats but I have a small head so brims tend to be rather large and annoying. So it takes a while before I find a hat I'm comfortable with. I mostly wear beanie hats, knit hats. I started getting more graphic tees, that turned back into character t-shirts, cartoon, anime, video games shirts, to a small collection of skate shirts, flannel shirts, multiple jackets. A new obsession with thermals. All in all, I think some parts of my original "style" still exists, but it evolves and changes over time as I change.
At the moment, I'd say I'm more of a hybrid hipster-nerd. For some reason, I've never been able to get away from the "nerd" aspect of my personality and style. But I do think my style has been influenced by the people, the course of my life, and how I feel about myself. I think many things play into how we present ourselves to the public.
