formal kimono with patterns at the hem; married woman's ceremonial kimono
A type of formal kimono worn by married women, typically pastel-colored with designs only along the bottom skirt. Worn at weddings and other ceremonial occasions.
My mother attended the wedding wearing an irotomesode.
The irotomesode is one of the most formal attires for married women.
Compound of 色 (iro, 'color'), 留 (tome, from 留める 'to fasten', referring to the shorter sleeves of a married woman's kimono), and 袖 (sode, 'sleeve').
