A lightweight, two-button jacket that is perfect for everyday use, made from a blend of polyester and cotton-polyester yarn, which is partially made from plant-based raw materials. The bellows shape created by Steam Stretch (*) is placed on the sides of the waist, and the design combines beautiful lines and stretch when worn. *A manufacturing method that shrinks cloth by applying high-temperature steam to create a unique stretch material. A thread that shrinks when heated is woven together with other threads, and when steam is applied, only that thread will shrink. By shrinking only the intended part of the woven cloth, three-dimensional patterns and shapes are created and the garment is completed.
