The typical length of the Umushana should be one that covers your shoes from your waist.
Pay attention to your pleats when draping your Umushana so you have a neat look and elegant carriage. It should go round your body with even and neatly tucked pleats, and be pinned securely and discreetly on your shoulder.
It is quite common, these days, for ladies to use brooches to pin their Umushana on their shoulders.
