 From the 1990s, it was generally accepted that the police could patrol in "shirt-sleeve order" which meant that they need not wear the jacket, as its widespread use was hampering in some situations.In 1994, the Home Office, with the co-operation of many chief constables, changed the uniform to black trousers, shirt, blue NATO-style V-neck jumper, stab vest (typically with pockets, pouches and other compartments), service belt (duty belt) and reflective jacket.Although there are minor variations in the styling, pattern and insignia, the police forces of Great Britain, Jersey, Guernsey, the Isle of Man and Gibraltar all wear very similar uniforms.
