The bigger, shinier, harrier sporrans seem to be restricted to full dress/ceremonial/traditional costumes. I've never seen anyone wear a mega-sporran casually, only in a pipe band, wedding or state function (but never a funeral; yes, they are ostentatious).

Why would someone wear a mega-sporran? Because tradition demands, in some cases. That's all. It's not a matter of taste. Left as a matter of taste, most have the sense and practicality to keep it simple.
