they are attached. Most collars are fitted to a jewel neck, a neckline sitting at the base of the neck all around; if the garment opens down the front, the top edges may be folded back to form lapels and a V-shaped opening, and the cut of the collar will be adjusted accordingly. Collar styles Names for specific styles of collars vary with the vagaries of fashion. In the 1930s and 1940s, especially, historical styles were adapted by fashion designers; thus, the Victorian bertha collar — a cape-like collar fitted to a low scooping neckline — was adapted in the 1940s but generally attached to a V-neckline. Some specific styles of collars include: Buttoning Conventions on fastening the buttons on a collar differ globally. In the United States and the United Kingdom, the top button is virtually always left unbuttoned, unless one is wearing a necktie, but unbuttoning two or more buttons is seen as overly casual. By contrast, in Slavic countries, including at least Poland, and Ukraine, the top button is buttoned even in the absence of a tie. Extended meanings From the contrast between the starched white shirt collars worn by businessmen in the early 20th century and the blue chambray workshirts worn by laborers comes the use of collar colors in job designation, the "workforce colorwheel". Examples are blue-collar, pink-collar and white-collar.
