A V-neck undershirt is a garment that typically features a deep V-shaped neckline that extends down to the chest area. This type of undershirt is designed to be worn underneath other clothing to provide an additional layer of coverage and comfort, and to prevent the outer garment from rubbing against the skin or causing irritation. The V-neck design of the undershirt allows it to be worn discreetly underneath low-cut tops or dresses without showing. V-neck undershirts are commonly made from lightweight, breathable materials such as cotton or spandex and come in a range of colours to match different skin tones and clothing styles.
