Main Difference
The main difference between Blouse and Tunic is that the Blouse is a women’s garment for the upper body and Tunic is a simple T-shaped or sleeveless garment, usually unfitted, of archaic origin
Blouse
A blouse (English: , , or ) is a loose-fitting upper garment that was formerly worn by workmen, peasants, artists, women, and children. It is typically gathered at the waist or hips (by a waistband or belt) so that it hangs loosely (“blouses”) over the wearer’s body. Today, the word most commonly refers to a girl’s or woman’s dress shirt It can also refer to a man’s shirt if it is a loose-fitting style (e.g. poet shirts and Cossack shirts), though it rarely is. Traditionally, the term has been used to refer to a shirt which blouses out or has an unmistakably feminine appearance.
The term is also used for some men’s military uniform jackets.
Tunic
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.
