Abstract
Slashes, deprived from the Crusaders' military uniforms, take their places among the fashion terms in modern fashion, and they are represented with some techniques such as fraying fabrics or making holes. Slashes are also used in various ways across all the fashion areas including clothing to accessaries. Slashes, which were once used to represent a solid body and to make a body move suitably, are used not only to express the formative of clothing but also to allow wearing sensations and functionality to wearers depending on their daily lives and the movements of their activities in modern fashion design. Optical illusions of fashion, image variabilities, functionality and ornamentation, and design principles, which were once represented with materials, colors, and details mainly used in fashion designs, are represented using slashes in modern fashion.
