That looks great!!! Sorry, I can't offer any advice on the drag lines, I've only just learned what the hey they are!Again, looks great!
What happens if you were to insert a small shoulder pad? Does that "lift" the shoulder and eliminate the drag lines (if I'm interpreting the correct drags lines to which you refer).
Much better!I eliminate the drag lines, I think you need to lower the underarm point, and lower the shoulder point.
Wow, your muslin is really looking good. i am with Sherry on the drag lines in the back. You may find, after lowering the underarm and shoulder point, that you need to shave off a bit of the armscye. Perhaps there is a little too much fabric there.But the good news is that this is a sleeveless design, so you'll be good to go! No sleeve alteration :)
