Collapsing Jacket Back: Side Seam Correction – ISOT Bonus Lesson 34 – Part 3 – Pagoda Model

This part of ISOT Bonus Lesson 34 of the Pagoda Model explains advanced jacket fitting corrections, with a main focus on correcting a side seam bubble. Reza shows how a curved side seam on the side panel of a jacket can create a positive surface shape. When the jacket is fitted closely against a flatter back, that extra roundness has nowhere to go and the bubble collapses. The correction shown in this lesson straightens the side seam so both side seams form a flatter surface shape when they are sewn together. This lesson also includes dropping the front and raising and narrowing the armhole to improve forward and backward arm movement without losing the close fit of the jacket. The purpose is to show how each alteration changes the jacket pattern and how those changes affect the actual Pagoda jacket on the body. This lesson shows the complete fitting logic: the visible fault on the body, the animated pattern correction, the cutting or alteration principle behind it, and the result after the correction has been applied. In this lesson, you will see: • How to drop the front of the jacket • How to raise and narrow the armhole for better forward and backward arm movement • How a curved side seam can create a positive surface shape • Why a side seam bubble can collapse on a closely fitted jacket • How to straighten the side seam on the side panel • How side seam shape affects the surface of the jacket • The before-and-after result on the actual Pagoda jacket This is Part 3 o
