タイトルまたは説明

A T-shirt (or t shirt, or tee) is a style of unisex fabric shirt named after the T shape of its body and sleeves. It normally has short sleeves and a round neckline, known as a crew neck, which lacks a collar. T-shirts are generally made of a stretchy, light and 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. Most modern versions have a body made from a continuously woven tube, produced on a circular loom, such that the torso has no side seams. The manufacture of T-shirts has become highly automated and may include cutting fabric with a laser or a water jet.

The T-shirt evolved from undergarments used in the *9th century and, in the mid**0th century, transitioned from undergarment to general-use casual clothing.
