While I do agree that the fly plaid (worn as a fly plaid) looks a tad dainty as a piece of daywear, when carried as a day plaid or at least properly kept under control, it looks more proportional than the full day plaid, which has the tendency to appear oversized. In fact, when carried on one shoulder, it seems to almost belong there.

I will agree that it could stand to be larger, perhaps six feet square.
