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. 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. They are typically made of cotton textile in a stockinette or jersey knit, which 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. T-shirts are inexpensive to produce and are often part of fast fashion, leading to outsized sales of T-shirts compared to other attire. For example, two billion T-shirts are sold per year in the United States, or the average person from Sweden buys nine T-shirts a year. Production processes vary but can be environmentally intensive, and include the environmental impact caused by their materials, such as cotton which is both pesticide and water intensive.
A hoodie (in some cases it is also spelled hoody and alternatively known as a hooded sweatshirt) is a sweatshirt with a hood. Hoodies often include a muff sewn onto the lower front, and (usually) a drawstring to adjust the hood opening. It covers most of the head and neck and sometimes the face. Hoodies may be worn for protection against the environment (cold weather, rain, etc.) Hoodies have become a mainstream fashion in the U.S., transcending the clothing item's original utilitarian purpose, similar to jeans. This clothing item has found its way into a variety of styles, even so far as to be worn under a suit jacket. Hoodies with zippers are generally referred to as zip-up hoodies, while a hoodie without a zipper may be described as a pullover hoodie. Throughout the U.S., it is common for teenagers and young adults to wear sweatshirts—with or without hoods—that display their respective school names or mascots across the chest, either as part of a uniform or personal preference. The hooded sweatshirt is a utilitarian garment that originated in the 1930s for workers in cold New York warehouses and thus have been around for over 80 years. In the 70s and 80s, hoodies were adopted by hip hop culture as a symbol of what one reporter termed "cool anonymity and vague menace" When the garment was depicted in FBI composite drawings of Unabomber Ted Kaczynski, the hoodie became linked to "seedy threatening criminality," thereby further asserting its non-mainstream symbolism.
Sweatpants are a casual variety of soft trousers intended for comfort or athletic purposes, although they are now worn in many different situations. In the United Kingdom, Ireland, Australia, New Zealand, and South Africa they are known as tracksuit bottoms. In Australia and New Zealand, they are also commonly known as track pants, trackies or tracky daks. Sweatpants are usually made from stretchy knitted jersey fabrics of differing weights, including single jersey, double jersey, fleeceback jersey, and loopback jersey (terry). They are a pull-on style pants and often have a flexible elasticated waistband with a drawstring closure. They may or may not have a fly and pockets. Some sweatpants can also feature elasticized cuffs at the hem of the leg. Sweatpants are traditionally ash gray in color but are now available in most colors. Traditionally quite "baggy" and loose, sweatpants are now also available in more form-fitting shapes; moreover, they have flexibility and comfort.
