This book sets out for students and professionals the practical principles and applications of pattern grading for men's clothing. The first chapters examine some examples of international sizing systems, develop the methods of calculating and validating the grading increments from a given size chart and demonstrate the working methods for manual grading. The main part of the book presents, in a simple stage by stage format, the applications of the system to a comprehensive range of men's garments. This is followed by a section containing examples of grades for styled garments, and each demonstration is preceded by a short discussion of the practical considerations involved. Finally the state of the art of computerised grading is explained and the latest developments in fully automatic grading are discussed, with some examples. A unique feature of this book is that some of the grading demonstrations include the grades for linings, fusibles and pockets, etc. How garment manufacturing technology influences specific aspects of pattern grading is also discussed.
