The main difference between Shirt and Tunic is that the Shirt is a garment for the upper body and Tunic is a simple T-shaped or sleeveless garment, usually unfitted, of archaic origin.
A shirt is a cloth garment for the upper body (from the neck to the waist).
Originally an undergarment worn exclusively by men, it has become, in American English, a catch-all term for a broad variety of upper-body garments and undergarments. In British English, a shirt is more specifically a garment with a collar, sleeves with cuffs, and a full vertical opening with buttons or snaps (North Americans would call that a “dress shirt”, a specific type of “collared shirt”). A shirt can also be worn with a necktie under the shirt collar.
A tunic is a garment for the body, usually simple in style, reaching from the shoulders to a length somewhere between the hips and the knees. The name derives from the Latin tunica, the basic garment worn by both men and women in Ancient Rome, which in turn was based on earlier Greek garments that covered wearers’ waists.
