why do men wear them, a bad fitting one looks so funny, do u honestly think they think people cant tell

A bloke on the train wears a syrup. It's the wrong colour and just looks wrong. I'd go bald or get that weave in stuff.

You only know it's a wig if it's badly fitted, good quality wigs are available now that can be indistinguishable from the real thing, if fitted by a professional.
