Sleeve Theory in Tailoring: Armholes, Pitch Marks and Sleeve Hang – ISOT Lesson 32

This lesson explains the theory behind tailored jacket sleeves. Reza explains the main factors that affect the shape, hang and fit of a sleeve before the practical sleeve-basting lessons begin. The purpose is to understand how sleeve depth, crown shape, top sleeve, under sleeve, seam position and sleeve pitch work together when setting a sleeve into a tailored jacket. This is not just a general sleeve explanation. It gives students the foundation needed to understand why sleeves are difficult to fit, why poor sleeve explanations lead to confusion, and how the position and rotation of the sleeve affect the final result on the body. In this lesson, you will see: • How tailored sleeves can be understood in a simplified way • How sleeves develop from simple shapes into complex jacket sleeves • What sleeve depth means • How sleeve crown shape affects the sleeve • The difference between the top sleeve and under sleeve • How sleeve seam position affects construction • What sleeve pitch means in tailoring • Practical exercises for understanding sleeve rotation and arm position This is ISOT Lesson 32 in Module 1 of the ISOT Online Coat Making Course.
