Englishwomen tailored gowns? It will surely be below the knee (7)
I believe the answer is:
hemline
'knee' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hemline that I've seen before include "Level to which skirt hangs" , "Lower edge of a skirt" , "Lower end of garment" , "low level of fashion?" , "bottom of dressed" .)
