nightshirts

Nightshirts are a form of sleepwear consisting of a loose-fitting, knee-length or longer shirt worn for sleeping. They are typically cut like a shirt and may have a collar, buttons at the front, long or short sleeves, and sometimes a pocket. The hem usually falls between the knee and the ankle, depending on style and region. They are designed to provide coverage and comfort without constraining movement, and are often worn without a separate top layer in warmer weather or with a robe in cooler weather.

Common materials include cotton, cotton blends, flannel, linen, and silk for luxury variants. Cotton is favored for breathability, while flannel adds warmth. Care generally involves machine washing, with care labels for heat and drying.

Historically, nightshirts have been worn in Europe and North America since the 17th century as everyday sleepwear for men and women, often made of linen or fine cotton. In the Victorian era, long linen nightshirts were common and sometimes elaborately tailored. In the early 20th century, pajamas became popular in many markets, leading to a decline in the use of traditional nightshirts, though they remained in use in some households and were occasionally worn by children or as nighttime lounge wear. In modern fashion, nightshirts persist as casual or retro garments, and some styles are unisex.

Design variations include button-down or pullover fronts, differing sleeve lengths, and prints or embroidery. Some cultures also use looser tunic-like sleepwear that function as nightshirts. They are often paired with robes or nightcaps in historical depictions.
