Apparently Enid Gilchrist was an Australian fashion designer who became well-known for her numerous self-drafting pattern books which were popular in the 1950s to 1970s.
After studying dress design at Melbourne Technical College, during World War II she worked as a dressmaker for a pattern firm. She then made her own patterns, and later joined New Idea magazine, where she published sewing books showing clothes which people could make up from the pattern drafts.
Here's one I'd love to draft up:
The intro reads: "Nothing could be simpler to make than this little nightgown, but if you invest in some really exquisite lace motifs, it could be the most glamourous piece in your trousseau."
Hhmm, I will try and aim to work on my trousseau early Spring!
