/cgl/ - Cosplay & EGL

I’m trying to alter a blouse pattern to fit and from experience I know I’ll probably need to widen the shoulders a little bit, but I’m not sure where the shoulder seam is actually supposed to sit on the body. All I can find are guides for men like pic related. Does this apply to women’s blouses too? I’m a little worried that men’s shoulder seams might be put further out to accentuate wide shoulders when that’s the opposite of what I want to do. The drawings on the pattern I’m using actually look more like the left picture. Is that sloppiness on the part of the artist or is there really a difference here?
