This jacket was inspired by one of our favorite Japanese pattern designers Iroha. Unfortunately she has shut down her shop and is no longer offering patterns. The pattern is really quite simple though, just two rectangles.
Marie' and I will work on our own instructions and recommended measurements if there is interest here.
This one was made out of a cotton/Lycra interlock from Yellow Bird Fabrics in Salt Lake City. I'm offering a bunch of photos here so you can see how the jacket changes to the shape of the wearer (please excuse the awkward modeling and photo taking skills of my 5 and 7 years olds).
Drapes over the shoulder:
Would love to make another one out of this from Emmaonesock.
