Some days a suit is too much. A good shirt is then sufficient to look dressed and powerful. Smart casual shirts can be made in many types of fabrics. Think of knitted, jersey, coarser oxford, thicker cotton, flannel, denim and prints. And then of course we have linen in the summer and combinations of linen and cotton. For your casual shirts, stay away from popelines and twill because they are too thin or have too much shine. The quality of the shirt becomes even more visible. Shirts become even more casual with a loose interior in collar, cuff and frame (unglued), other buttons (for example brown mother-of-pearl or horn), pleated sleeves and more visible topstitching. In addition to the standard white, light blue and striped shirts, you never have enough shirts.
