The design of geometric form is widely used in daily life, such as Product Design, Communication Design and Digital Animation. In fact, it is an indispensable element of artistic creation. However, there is still a large possibility to explore for clothing design. This study discusses the relationship between the features of geometric form and clothing patterns. Through the works of fashion designers analyse the techniques used and the possibility of development. In order to break the traditional concepts of pattern making and to dismantle the patterns, the geometric form was used as the basic structure to create a three-dimensional silhouette. As a result, the clothing would produce visual effects with the movement of body. The overall design process and creative outcomes contribute researchers different design thinking for further study and development.
