Abstract: Abstract: The shear design of pattern is a method commonly used in garment structure design,which plays an important role in shaping the apparel modeling . With the continuous development of costume design, costume modeling is becoming more and more diverse, in order to adapt to these changes, the pattern design methods are also more and more. Based on the analysis of common and novel fashion apparel modeling pattern ,shearing method and its subsequent spread was classified, the shearing method for edge shear, internal shear and total shear, follow-up development mode is divided into parallel expansion and rotation expansion , and expatiates the shear and unfolded principle, analysis their methods of implementation using case , especially tests by fabric for new fashion styles of shear design , so provides reference of the corresponding shear method for the complicated modeling clothing.

Key words: pattern cutting design , fashion modeling , cutting method , spreading method
