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.
A sweatshirt is a long-sleeved pullover shirt fashioned out of thick, usually cotton cloth material. Sweatshirts are almost exclusively casual attire and hence not as dressy as some sweaters. Sweatshirts may or may not have a hood. A sweatshirt with a hood is now usually referred to as a hoodie, although more formal media still use the term "hooded sweatshirt". The sweatshirt's potential as a portable advertising tool was discovered in the 1960s when U.S. universities began printing their names on the medium. For students and parents alike, university names on sweatshirts became the preferred casual attire for exhibiting school pride. The sweatshirt, along with the T-shirt, provided a cheap and effective way of disseminating information on a mass scale. The T-shirt slogan fad of the seventies inevitably translated to sweatshirts. Due to the relative simplicity of customization and the power of clever graphics combined with catchphrases, sweatshirts became a vehicle for personal expression for both the designer and the person wearing them. In Australia, the sweatshirt is referred to as a 'Sloppy Joe'.
Yoga pants/gym Leggings are high-denier hosiery reaching from ankle to waist, originally designed for yoga as exercise and first sold in 1998 by Lululemon, a company founded for that purpose. They were initially made of a mix of nylon and Lycra; more specialised fabrics have been introduced to provide moisture-wicking, compression, and odour reduction.
A sleeveless shirt is a shirt manufactured without sleeves, or whose sleeves have been cut off. Depending on the style, they can be worn as undershirts, worn by athletes in sports such as track and field and triathlon, or as casual wear. In the United States and Canada, any casual sleeveless shirt can be called tank top or tank shirt, with several specific varieties. It is named after tank suits, one-piece bathing suits of the 1920s worn in tanks or swimming pools. The upper garment is worn commonly by both men and women. The build of a tank top/singlet is simple: the neck and armholes are often reinforced for durability. One usually has large armholes and neck holes and a neckline that can reach down as far as the bottom of the chest. (Women's tank tops have smaller holes, to conceal their breasts). They are also sometimes made long to make tucking into pants easier. In almost all cases, they are buttonless, collarless, and pocketless. A sleeveless T-shirt, also called a muscle shirt, is the same design as a T-shirt, but without sleeves. Some sleeveless T-shirts, which possess smaller, narrower arm holes, can be worn by both women and men, usually with sports bras underneath for women. They are often worn during athletic activities or as casual wear during warmer weather. They are colloquially known as shooter shirts in the southern United States. They were quite popular in the 1980s and were commonly associated with surfers and bodybuilders (hence the name "muscle" shirt) and often bore the names and logos of gyms. Such shirts without logos are now more commonly worn as casual wear.
Nursing bras are a type of nursing wear. A nursing bra is a specialized brassiere that provides additional support to women who are lactating and permits comfortable breastfeeding without the need to remove the bra.
