Based on the common British trousers in the early 20th century.
In the past, the waist connected tailoring used in hand-made clothing, Annual Ring also uses this cut. This kind of design without independent waistband first appeared in England. It was easy to see in tailors from the end of the 19th century to the beginning of the 20th century. This classic design was also used in British 37 style trousers in the 1930s. In the United States in the 1940s, this type of pants was developed. The downward position of the pants' ears, with a narrow pair of belts, and the proportion of the chest and waist was expanded, making the legs appear more slender. Since there is no independent waist, comfort is greatly increased. This kind of trousers design on the west coast of the United States is also known as "Hollywood waistband", which is very popular in the 1940s and 1950s.
Due to the thick Tweed Fabric, changed the trim waistline into a high-density twill waistline to increase comfort and retain the classic design. The trousers have enough loose rungs, and the straight tube of trousers is slightly loose, which is more suitable for daily wear. The classic details of double pleats were conventional from the 19th century to the beginning of the 20th century. Instead of the design of Hollywood waistband moving the pants' ears down, placed them on the regular waist to ensure that the thick tweed would not sacrifice its basic comfort.
