What Is a Dress Shirt? The Foundation of Formal and Business Attire

The semi-spread collar (also called a moderate spread or Kent collar) is the most versatile option because it works equally well with ties of various widths and looks polished when worn open-necked without a tie. The spread is wide enough to accommodate a standard four-in-hand knot, a half-Windsor, or a full Windsor without the collar points being pushed apart awkwardly. It also frames the face attractively on most face shapes. Point collars, while classic, tend to look dated and are less flattering for round faces. Wide spread collars make a strong fashion statement but can overwhelm narrow faces and require larger tie knots to fill the gap. For someone building a dress shirt wardrobe from scratch, starting with semi-spread collars across all shirts provides maximum flexibility.

The right fit depends on your body type, comfort preference, and whether you will wear the shirt with or without a jacket. A slim-fit dress shirt has less excess fabric through the torso, creating a cleaner line under a suit jacket — this is ideal for lean to average builds and prevents the billow of excess fabric above the trouser waistband. A regular-fit shirt offers more room through the chest and midsection, which is essential for comfort during long days and for athletic or larger builds. The critical fit points to get right regardless of cut: the collar should allow two fingers between your neck and the closed collar; shoulder seams should sit at the edge of the shoulder bone; the shirt should be long enough to stay tucked during a full range of motion. If you frequently wear jackets, lean toward slim; if the shirt will be your outermost layer, fit for standalone comfort.
