This is McCalls 7365. It was a bit of a slog. There are 88 steps in the instructions, only a few of which are inapplicable to View C which is the one I made.
I fell for the complex lines of this shirt, which are of course all revealed by the sheer white fabric McCalls chose for it. Mine on the other hand is embroidered black linen, very lightweight but still... linen. From deep stash of course.
I made size 10 but think it's a bit too big on me.
