I have started seriously thinking about changing my attire as normal clothes do not really fit me any more. For instance sitting down while wearing jeans makes me feel very constricted at the thighs region. Also when I wear a pullover, putting my jacket on top seriously restricts my arms movement.

Fortunately, there are places where one can get the right kind of clothes:
