Plaid shirt is undoubtedly a necessity in the whole plaid fashion, because it is casual, versatile, intimate and warm. The season most suitable for plaid shirts is naturally autumn. Pick a plain one, match it with a narrow straw hat and jeans, and go outside or in a world of golden yellow or crimson but always with a clear sky. Before the cold winter comes, run and laugh. Yes, this is the keynote of the plaid shirt-born for freedom and laughter.
