Abstract
This study selected and compared 7 tailored collar making factors from 15 clothing construction university textbooks. According to the results, in 15 clothing construction textbooks, the neckline of a tailored collar was drawn at the same length as the back neck circumference of the bodice and the length of collar stand was 3cm in 10 textbooks. In addition, the length of the collar laying varied between 2cm and 4.5cm regardless of the width of the upper collar or the textile thickness. In 7 out of the 15 textbooks, the gorge line of the collar was drawn by illustrating the collar pattern on the bodice based on the roll line and then copying it symmetrically. On the other hand, the pattern of upper collar was made in 5 ways; and 2 books did not give any explanation in the sections dealing with patterns or sewing. In addition, 6 textbooks explained that inner and outer collars are sewn with a difference. The lapel pattern of the facing part was made in 4 ways; in addition, 3 textbooks did not provide an explanation and 4 books explained that the difference is given in the sewing. The textile thickness and elasticity need to be considered in collar pattern making; however, they were not specifically mentioned in most of the textbooks.
