I have used the round earth pattern for a hakama (have made two now, and they came out pretty well. I didn't realize that you were involved in creating it Janet- I had thought that Carol Shifflett was the author. Anyhow, I made one with an extended front so it can be tucked into my obi without sagging at the side. It does confuse students who are folding it for me occasionally though.
I have also made dogi pants from Simplicity pattern 8840 from 1988. It is not very authentic, but with a few changes and extra patch over the knee area, it makes a reasonable pair of pants. I've never attempted a jacket, cause I am not sure where to get the material.
