Very helpful information. Thank you very much for being selfless and sharing your knowledge. Can you please just clarify the Off the Shoulder [OS] sleeve part for me a bit. Specifically: (1) how / where should the round shoulder measurement be taken (e.g. should it be the horizontal circumference taken from the topmost part of the shoulder at the arms)? (2) where on the pattern should the calculated measurement (for the OS sleeve) be applied (e.g. should it be the length / measurement from the previously marked OS neckline point at the shoulder to the point where it essentially ends on the arm)? Thanks again and God bless you!
