drop from collar to hem; collar-to-hem measurement
Used for kimono, yukata, and similar garments. Refers to the vertical distance from the back collar (衿) down to the bottom hem.
I had the kimono made with a longer collar-to-hem drop.
This yukata's collar-to-hem measurement is too short, so the hem rides up when worn.
Compound of 衿 (eri, 'collar') and 下 (shita, 'below'). The reading えりした is a straightforward combination of the two components.
