This is a gorgeous vintage silk kimono nagajuban from the 1930s! It is made of bright red-orange silk printed with a diamond pattern. It does not have a haneri collar attached. It is lined in red cotton.
It is in very good condition, I can only find a few faint spots and one round stamp mark on the inside of the lapel that has faded on to the outside of the other lapel, shown in the last photo.
Measurements are approximate, taken flat and then doubled where necessary. See last photo for diagram to explain how measurements are taken.
Length from shoulder to hem: 48 inches Around body: 46 inches when flat and overlapped as in the diagram Sleeve to sleeve width: 49 inches Sleeve length: 21 inches
