The pattern preparation is the most important where the ready-made clothes depends on. This stage has the success of the designation and all process. A new ways were used to produce the clothes one of them is the flat pattern which based on ratios to identify the relationship between the twirl of chest and other measured twirls like waist, buttocks, and neck. Previous researcher (Ayda Nassar, 1987) mentioned that the pattern based on codified ratios for woman body, helped to assess the needs of ready-made industry where, it provides the speed in delivery and simplification at work. Patterns are differed in how to highlight a précised particular design because of the different ways of the origin pattern. Hence;                                                       the importance of find out the problems that appears when implementing the industrial pattern and the pattern formed on mannequin by developing patterns for different designations through both ways and comparing between them in the terms of pressure on the body and identify the simplified in usage. This research aimed at identifies the best way in developing the industrial pattern (flat) and the pattern formed on mannequin and identifying the advantages and disadvantages for each way in implementing the selected designs, and choose the suitable one. The results revealed that the pattern formed on mannequin is better than the industrial pattern in implementing selected designations respecting to Size (L).
