The formal shirt is the garment closest to your face and the one whose quality is most immediately apparent to anyone paying attention. The collar should hold its shape without a stay. The fabric should breathe across a long day without wilting. The cuffs should sit correctly beneath the jacket sleeve without tugging. These are formal shirts from Alessandro Gherardi, Canali, and others who have spent a great deal of time thinking about exactly these things and know how to resolve them. The foundation of a great many outfits that appear to require very little effort.
