Below we have some tips about shirts whose details, fabric and pattern give different impressions and different degrees of formality. For example, button down collars are best buttoned-up, without a tie. In brief, the larger the collar spread or angle between the collar tabs, the better the shirt lends itself to being buttoned up with a tie. The business shirt often has more toned-down colours and patterns, where a white and light blue garment creates a good base wardrobe. Add an overshirt, denim shirt, flannel shirt and/or corduroy shirt for an even more varied shirt wardrobe.
