I have finished!
Bootstrap 45179 is the pattern I used:

Strangely, I discovered last night that I already owned Style Arc Kristin, which is almost identical, although without the yoke. At some point I will have to make it to compare!
My first garment is almost as the pattern shows it, in a cotton lawn from my stash that probably came from Doughties. I lengthened it, because nobody wants to see my knees, and I omitted the zip because I find I rarely need them. In terms of fitting I narrowed the shoulders, took in the sides and shaped the back seam, which made it less sack-like. I added trim to the edge of the yoke because the feature was lost in the pattern, and balanced it with trim on the pockets. This was the result:

The second version was tunic length, made in another fabric from my stash, a very cheap denim from Fabric Guild which, from the feel of it, has quite a high proportion of manmade fibre, and is quite soft. In terms of fitting I narrowed the shoulders and shaped the sides a little, but kept the back seam straight because the fabric has good drape.
I embroidered around the neckline, so I didn't include the yoke, but shaped the neck to match the line of the embroidery, and faced it. I originally intended to add a peplum and gathered ruffles to the sleeves, but pinning the gathered peplum showed that the fabric really wasn't suitable so I kept it simple, not wanting to look like a wide triangle. Fortunately I had cut the front and back long enough to keep it tunic length, with the hem slightly lower at the back, even without the peplum.

The third and final garment was another top, this time in a cotton voile from Minerva - also from my stash (3 out of 3 - go me!) I didn't do the yoke because I felt the fabric was too fine, so I faced it again, with a slightly lower, round neck. I narrowed the shoulders again and took the sides in a lot more above and at the waist, and flared it out a lot below the waist. I also curved the hemline, and I added an ungathered flounce with a short slit to each sleeve.

I am pleased with all three, but I absolutely love the third one.
