A sleep shirt is a type of loose-fitting garment designed for comfort during sleep. Typically made from soft fabrics like cotton or modal, it allows for ease of movement and breathability. Sleep shirts often come in various lengths, from knee-length to mid-thigh, and can feature short or long sleeves. These shirts are popular among both men and women and can be worn alone or layered with other sleepwear. They are available in a range of styles, colors, and patterns, making them a versatile choice for nighttime attire. Many people prefer sleep shirts for their relaxed fit and cozy feel.
