A blouson or blouse jacket is a jacket that is drawn tight at the waist, causing it to blouse out and hang over the waistband. Some of them have a hood. It takes most of its modern traits from the American flight jacket and police blouson. It is related to the Eisenhower jacket. It is considered to be both sportswear and casual civilian clothing.
The Black jacket was popularized by Yves Saint Laurent and was donned by some music groups in the late 1950s and early 1960s. Modern flight jackets have been popular with skinheads and scooterboys from the 1980s onwards.
The blouson jacket has been worn by several police departments in the United States, Austria, Israel, New Zealand, Germany and the United Kingdom due to its sturdy design, and heavy insulation. The NYPD has used a form of them, since 2010.
