I have a question, seamstresses.

Instead of using elastic in the neckline of the dress (view A), I'm doing stationary gathers, with a bias binding.

Shouldn't those gathers over the shoulders be a little looser than those on the front and back?

And, (I should have thought of this earlier) shouldn't I stitch the left front facing down an inch or so from the edge to help support the base of the snaps?
