I would say a nice pair of shoes and some shorts would be good. Black shoes or boots would work well. I hate being infected as well, it's very hard to work with some diseases, especially mine =/
Ah I see. In that case, I would suggest finding a messier hair style. The hair you have now, although wavy, looks too neat. Try to find something where the hair looks more out of place.
Perhaps use a set of eyes with eyebrows, the browless look is a little odd. I also think the stockings are too white, they're a bit blinding.
