For at least half my life, my style of dress was painfully dull, even slobby. I think I've posted about it before - two colors of slack pants, three colors of plain t-shirst, the same faded black hat that I wore so I didn't have to wash and do anything with my hair, blah, blah, blah. It got so bad that my hygiene suffered, as well. I would go for extraordinarily long periods of time without brushing my teeth, for example. That particular habit has led to other problems, as one might deduce.
Anyway, it's only been very recently that I completely changed my whole wardrobe and style. It's given me a little more confidence, though not enough to even begin to overcome my anxiety.
