Well, I am one out of two there. I CAN iron a hakama, but I really dont see why anyone would need to. All the hakama I have had have never needed it. The fabric is heavy enough to not wrinkle much, and hanging takes care of the rest.
The hakama of the 1950s were not like the fabric of today - we often compared the material to a secondhand army blanket.
