Taking the shape of the body
Unfolding the body
Translating the sleeve/shoulder blade/waist/armpit panels into a first attempt at a wearable blouse
First toile of the blouse
Fit adjustments for shoulder and armpit
Creating the pattern with the arm in an upright position creates a narrow shoulder, a lot of volume in the armpit and a short length from neck to shoulder. In order to wear the blouse with arms down I opened up the top of the shoulders and added the needed space in the pattern.
