I have focused on making an AANS uniform, as thanks to the mini-series Anzac Girls, based on the book The Other Anzacs by Peter Reese, I managed to make a detailed study of the costumes made for it.

The rest of my research showed a lot of variation in uniform styling, and I am yet to find a set of actual uniform guidelines for any of the nursing services, so as far as I know it was anything goes as long as it was tidy.
I had hoped to have the entire uniform finished by this Anzac Day, but working six days a week for the past two months hasn't left a lot of extra time for sewing. What I do have today though, is the finished underdress. It should be a darker shade of grey and the skirt isn't quite long enough due to fabric restrictions, but here we are. I ended up using Simplicity 9723 as a general base.
