Typically made of cotton textile in a jersey knit, it has a distinctively pliable texture compared to shirts made of woven cloth. The majority of modern versions have a body made from a continuously woven tube, on a circular loom, so that the torso has no side seams. The manufacture of T-shirts has become highly automated, and may include fabric cutting by laser or water jet.
The T-shirt evolved from undergarments used in the 19th century, and in the mid-20th century transitioned from undergarment to general-use casual clothing.
A V-neck T-shirt has a V-shaped neckline, as opposed to the round neckline of the more common crew neck shirt (also called a U-neck). V-necks were introduced so that the neckline of the shirt does not stand out when an outer shirt is worn over it, thus reducing or eliminating the visible cloth above the outer shirt of a crew neck shirt.
