How to Correct Jacket Fitting Problems on the Pattern – ISOT Bonus Lesson 34 – Part 2 – Traditional

This lesson shows how to apply 18 jacket fitting corrections to the paper pattern of the Traditional jacket. Reza demonstrates how to transfer the fitting decisions from the fitting room back onto the paper pattern, so the jacket can be corrected before the next stages of construction. The purpose is to show how fitting alterations are not only judged on the body, but also translated accurately into pattern changes. This is the second part of the Traditional Model fitting-room sequence. Part 1 showed the fitting problems, pattern corrections and before-and-after results on the jacket. Part 2 shows how those corrections are applied step by step to the paper pattern, including balance changes, seam displacement, side seam corrections, armhole corrections, sleeve corrections, pitch mark changes and break line adjustment. This is not just a pattern alteration demonstration. It explains how to keep the pattern clean, how to draw correction lines properly, how to true the altered pattern and how multiple fitting corrections affect each other. In this lesson, you will see: • Which tools are needed for altering a jacket pattern • How to draw clean correction lines on the pattern • How to apply 18 fitting corrections to the paper pattern • How to correct balance, chest, side seams and underarm seams • How to reduce the armhole and sleeve head size • How to alter the sleeve for movement • How to re-mark pitch marks and the break line • How to true the pattern after all corrections
