A shirt is a garment for the upper body with sleeves and a collar. It buttons down the front, though some pull over the head. The shirt is a foundational piece in most wardrobes. It can be formal, casual, or somewhere in between. The same white shirt reads differently depending on the fabric, fit, and what it is paired with.

Types vary widely. The dress shirt is tailored and formal, often worn with a suit and tie. The oxford shirt is casual, with a button-down collar and thicker fabric. The flannel shirt is brushed cotton, warm and relaxed. The polo shirt has a collar and a short placket, no full button front. The tunic is longer and often worn untucked. The camp shirt has a relaxed collar and straight hem, common in warm climates. Each has its own conventions.

Fit matters. A dress shirt should allow movement without billowing. The collar should sit close to the neck but not choke. Sleeves should end at the wrist bone. The body should be neither too tight nor too loose. Off-the-rack shirts rarely fit perfectly. Tailoring can adjust the waist, sleeves, and collar. Fabric choices include cotton, linen, silk, and blends. Cotton is breathable and durable. Linen wrinkles but stays cool. Poplin is smooth and formal. Oxford cloth is textured and casual. Care depends on the fabric. Most shirts can be machine washed, but dress shirts often need ironing or professional pressing.
