Karaginu-mo
The terms Heian, Kamakura, Muromachi, Momoyama refer to historical eras. See the Japanese Historical Eras reference page.
Formal Heian wear. The first picture is actually a ceremonial garment that only would have been used a state ceremonies by the Empress or someone else important. The Karaginu is a "Chinese short jacket" that you can tell is not one of the usual layers by its collar that is not wrapped and not caught in an obi like the other layers. The mo is the elaborately embroidered white train that flows in the back.

Garments: (Kosode, nagabakama, hitoe, utsutsuginu, uchiginu, uwagi, karaginu, mo)
The colors of the layers were very important and ideally should match the season. Some of the many layers were faked by making one kimono body with up to 5 sleeves, collars, overlaps, and hemlines attached (the utsutusginu). Karaginu and mo were only worn by very high ranking ladies and for ceremonial events.
