Introduction:
A T-shirt, or tee shirt, is a style of fabric shirt named after the T shape of its body and sleeves. Traditionally, it 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.
Some modern versions have a body made from a continuously knitted tube, produced on a circular knitting machine, 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 19th century and, in the mid-20th century, transitioned from undergarment to general-use casual clothing.

Views & Review:
Very in looking T-shirt in every out fit…. Amazon is delivering original product as previously I have purchased same T-shirt from shop the quality is not good like this, I have wear this T-shirt several times then also the quality Remain
Quite happy with this purchase. I bought an XL and am a 6′ 1″ guy and though it fit a little snuggly on the first wear, it was stretched nicely after a day of wear. Very impressed with the quality of the fabric as well for the price point and I will be getting a bunch of these
