the seam is tilted bakwards.
the seam beginns at the same point as a normal shoulder seam should do.
meaning from collar stand to top center sleeve.
but in the ToD it was from collar and tilted away from top center sleeve.
the RED line indicates a normal shoulder seam to top center sleeve...the GREEN is the titlted backwards seam
get it?
I don't know. In the photo that DougC posted the shoulder and yoke seam a little more parallel than you depicted in your sketch. Seems to me that the shoulder seam starts more at the back of the neck at the collar stand, rather than at the side of the neck as we are all used to. The whole seam is further back on the.. err, back. Cutting it at a non-perpendicular angle to the shoulder hole seems like a very odd and non-standard way of constructing a shoulder (I've fiddled a little bit with clothing patterns.) I think you're being a bit fooled by perspective in that photo you traced over, because his shoulder is round and not a flat plane. The seam runs parallel to the slope of his shoulder, rather than angling across it.
I don't claim to be an expert, but I enjoy figure drawing and I pay a lot of attention to the form of the human body, and the way clothing drapes on it.
Just my opinion, but if you just take the regular, top-(or front)-of-the shoulder seam and move it backwards about two inches or so, without messing about with funky angles, you'll be good.
I can doodle what I think the seam arrangement looks like, if you'd like.
EDIT: Aw, heck. I'll just go with DougC's pic.
The blue line approximates where I think the seam for the collar stand sits. The red line is the top slope of his shoulder. The green lines are my best guess for the seam arrangement. To my eyes, the shoulder seam is parallel to Ford's shoulder, whereas your arrangement (in yellow):
would put it at an angle. And since we can see the seam and that it does not follow that particular line, it doesn't seem correct that the seam would be at the weird angle you propose.
But this is just what my eyes see based on the couple of pictures posted to this thread. Take it for what it might be worth to you.
