Silk, cotton (lining)
Stenciled warps and wefts (meisen)

The erratic colored ribbons that rhythmically peak and plunge along straight lines across this kimono design echo the waves that blip across the horizontal axes of oscilloscopes, which were invented in the early 20th century, but came into widespread use following World War II.

In the first photograph, it is clear that whoever sewed the panels together made the conscious decision to alternate the dark and light patterns at the center seam. Either way would probably have created an interesting effect.  The large waves and the small waves both move almost without interruption across the center seam.  The juxtaposition of two alternating color blocks (dangawari) is a time-honored Japanese textile tradition, so this kimono combines a bit of the old and a bit of the new.
