One kimono uses up an entire bolt of fabric measuring about 14 inches wide and 12½ yards long. It’s traditionally hand stitched. Today, it still requires a substantial amount of hand-sewing, even if a sewing machine is used.
Kimonos are “zero-waste” products as they contain a whole bolt of fabric without cutting. Although the garment uses a lot of fabric, the life of a kimono doesn’t end in a landfill.
Now, if that isn’t green, I don’t know what is.
