I've been too busy sewing to post!
One frock I've made is Butterick 5672
The fabric is a tweedy wool blend knit, with about 30% stretch across the grain. Not enough stretch for this dress, so I did put the zip in. I went up a size due to my fabric not being stretchy enough, but the pleats are pulling a little too much so it's probably still a skootch too small. Still it's comfy and may become a tripfit once I've road tested it.
