What is a kimono jacket called?

The kimono jacket is called a haori. It's a hip- or thigh-length jacket worn over a kimono, an article of traditional Japanese clothing. The haori is normally designed with a tiny collar and two thin, triangular panels sewed onto each side seam. Two short cords, known as haori himo, are normally tied in the front of the haori and attached to small loops stitched inside the garment.
