I wear a lot of purple shirts, and no-one really cares about men wearing pink, especially if it's a shirt. I usually wear whatever is nearest when I wake up, but that always includes jeans or brown chinos (because screw you they are comfortable). I will, however, immediately judge you if you wear a tracksuit bottoms (or maybe top) while not doing, going to, or returning from sports of some descriptions, if you wear burberry (is that how you spell it?) especially with a tracksuit, or anything that clearly states the name of the company that produces the clothing in huge letters on it (excepting footwear or sportswear, if you are wearing said sportswear for sports).
so, yeah, nothing too specific...
