Castles Edge Jersey A T-shirt (or t shirt, or t) is Castles Edge Jersey a style of unisex fabric shirt, named after the T shape of the body and sleeves. It is normally associated with short sleeves, a round neckline, known as a crew neck, with no collar. T-shirts are generally made of a light, inexpensive fabric, and are easy to clean. Typically made of cotton textile in a stockinette or 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.
