The ready-made garment industry is one of the most important pillars on which the industrial renaissance depends on the general level. There are new means and methods that must play their role in the garment industry, and the products must have the qualities and characteristics of quality necessary to meet the needs of the consumer. The concept of quality includes all stages of the production process that affect positively or Negatively on the quality of the final product, as the model preparation stage is considered one of the most important and accurate stages on which the garment industry depends, and the success of the design and production as a whole depends on it.
Through the foregoing, it is clear to us the necessity of developing and paying attention to the preparation of different models as a basic stage in the production process, using the theory of proportion and proportion in analyzing the lines of designing the women's jacket.
research aims:

Using the theory of ratio and proportion in analyzing the design lines of the women's bomber jacket
Implementation of the women's jacket using the theory of proportion and proportion in the research sample

research results

The study concluded that the design lines were analyzed and the lines transferred onto the basic pattern in an engineering manner using proportion and ratio to match the shape of the design.
There are no statistically significant differences between the averages of specialists' evaluation of topics and measures of agreement and difference for jackets and indices, if the theory of ratio and proportionality is used.
