Edwardian men’s shirts are similar to today’s dress shirts with a few major exceptions. For example, shirt collars were detachable so they could easily be laundered or replaced. You won’t find these easily today, so a white collar shirt in either round collar, club collar, or classic wide point collar over a thin vertical striped shirt is ideal. Edwardian dress shirts could be all white or a light solid color as well. Work shirts were usually a dark blue heavy cotton. Formal shirts were button downs with wingtip collars. Sweaters were plain color ribbed chunky knits in both pullover and cardigan styles.
All of these new shirts, vests, and sweaters are reproductions or new vintage-inspired styles that will work with your 1900 to 1910s Edwardian men’s fashion look.
