男西装是男士日常工作和商务活动的首选，是国际性服饰文化的典型代表，其服装版型一直十分受人关注。贴体型男西装正是受国际文化发展而流行起来的一种修身类西装，在男士中逐渐流行。然而，这种用于修身的西装款式由于前胸宽以及后背宽等结构处都制作的比较小，对于一些身材魁梧、体型较厚的男士而言，会造成紧绷、穿着不舒适的感觉，并且可能产生服装其他部位结构变形，从而在外形上不美观，因而，针对厚型体型的男士穿着的较贴体男西装后背宽进行纸样的优化设计，无论是对于舒适度还是美观度都较为重要。

Congruent-shape Business Suit for Man
Since man's business suit is the first choice for their daily work and commercial activities, and the symbol of international finery culture, the pattern of it has always attracted people's attention. With the development of international culture, congruent-shape-suit becomes popular among gentlemen. However, this style of man's business suit for perfecting one's shape, which the patterns of chest and back are made smaller, is a little tight and not so comfortable to strong and husky ones. At the same time, such conditions may also cause the distortion of other parts and destroy the slinky shape of the suit. When you design the congruent-shape-suit for strong and husky men, optimizing outturn sheet of a broad back is very important to comfort and beauty.
