Garments with wavy hems worn by a basket-maker (7)
I believe the answer is:
hosiery
'garments with wavy hems worn by a basket-maker' is the definition.
I can't tell whether this defines the answer.
'with wavy hems worn by a basket-maker' is the wordplay.
'hems' says to take the final letters (I've seen 'hem' mean this (hem can mean an edge of something)).
'worn by' is an insertion indicator (outside letters are worn by those on the inside).
'a basket-maker' becomes 'osier' (tree whose wood is used to make baskets).
The last letters of 'with wavy' are 'hy'.
'hy' enclosing 'osier' is 'HOSIERY'.
Can you help me to learn more?
(Other definitions for hosiery that I've seen before include "Stocking" , "Stockings etc." , "the object of much leg-pulling" , "Socks/stockings" , "Underwear items such as stockings" .)
