Pattern Review here.
Instagram, the consensus agreed with the lovely Carolyn to definitely not add a pleat as that would alter the classic sheath look. Barbara suggested a slight gathering eased into the facing and that is sort of what I did. I cut the facing a smidgeon (how's that for specifics!) shorter than the neckline and eased it in when stitching.
Using these resources below, it was oh-so-easy to put in. I especially liked the basting first idea from SunnyGal. That sort of stabilizes everything for the final stitching.

SunnyGal Studio: invisible zipper you don't scare me
Inside out front and back. Seams were 5/8" and the edges were serged then ironed open. I wore a slip underneath as there was not enough time for lining. Added a little hook and eye at the top of the invisible zip.
