The details of the pattern are based on formal trousers; after deconstructing the trousers, combining them with functional trousers and reshaping, the waistband is extended into a military-like structure, and the flips and the bottom pieces are combined with each other; a cutout design is formed on the side. In addition, the functional design of connecting the straps and the buckles makes the cutout with a looming visual effect while walking; the inner side is folded out using the paper origami technique, and a shirt button is attached. When the buttons are fastened, it looks like tapered trousers, and when left unbuttoned, it slits like the pages of a spread-out book.
