Sweaters are a versatile item of clothing and can be worn on top of almost any outfit. Sports sweaters, especially hoodies, are often worn on tops of sports kit while traveling to or from a sports ground. Sweaters can be worn with a dress shirt underneath (and optionally a tie), which has the advantage of allowing the wearer to have the option of removing the sweater when it is uncomfortably warm and still looking presentable in many situations. Layering and the ease with which it allows for temperature regulation is a major benefit of the sweater as an article of clothing. Various methods have evolved for conveniently carrying a sweater, once removed. The three most common approaches are: around the waist (either loin cloth, or knotted in front style) and over the shoulder. The origin of these styles are unknown, although the "knotted in front" style is widely agreed to have been developed in Miami, Florida in the mid 1970s.
