Take a summer knit hat, one of those vocaloid shirts, and beach sandals. You end up with a character that is somewhat similar to the way I dress.
The hat I usually wear is more like a newsboy/vintage golf hat, but it's the closest you can get to the hat I normally wear.
I almost felt like going on a tangent about the specifics of how I dress, but I don't think it'd be good to post here.
