jacket straitjacket https://en.wikipedia.org/wiki/Straitjacket https://www.wikidata.org/wiki/Q231647 A garment shaped like a jacket with long sleeves that surpass the tips of the wearer's fingers. Its most typical use is restraining people who may cause harm to themselves or others. Once the wearer slides their arms into the sleeves, the person assisting the wearer crosses the sleeves against the chest and ties the ends of the sleeves to the back of the jacket, ensuring the arms are close to the chest with as little movement as possible. straight-jacket straightjacket straitjackets
