It's finished now and to me, looks like a top with a smallish neckline. I did try it on Lola (in an attempt to console myself for spending many hours on this failed newborn gift!) and it does look completely adorable but when she moves it strikes me as being small enough around the neck to possibly annoy her. So to salvage it I will unpick the slip stitching on the inside yoke facing, turn it inside out and measure out half of the yoke width (which will neatly remove the top button hole too) and re-sew the neckline. A bit of a pesky job but worth it to end up with a lovely new top for Lola.

My first bound buttonholes! A bit fiddly for 10mm buttons but I'm ready for my next go.
As for the soon-to-be-born newborn gift, I thought try this Butterick 407 Scallop Bonnet:
