IPA: /ˈhɛm.laɪn/
KK: /ˈhɛmˌlaɪn/
The lower edge of a piece of clothing like a skirt, dress, or coat.
She decided to shorten the hemline of her dress for the party.
Hemline → The word is formed from "hem" (from Old English *hem*, meaning the edge or border of a garment) and "line" (from Latin *linea*, meaning a line or thread). The term "hemline" refers to the line formed by the edge of a garment, particularly the bottom edge of a skirt or dress.
Think of the 'edge' ('hem') of a garment and how it creates a 'line' — that's what a hemline is.
