Sleeveless shirts are a type of clothing that have no sleeves and are usually made of lightweight fabric. The two most common types of sleeveless shirts are TANKS and tanktops. TANKS are a type of shirt that typically have a wide neckline and are usually cut close to the body. Tanktops are similar to TANKS but usually have a more relaxed fit and wider armholes. Both TANKS and tanktops are popular summer fashion items and can be worn with shorts, skirts, or jeans.
