Sock pattern (6)
I believe the answer is:
argyle
'sock pattern' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for argyle that I've seen before include "Diamond-shaped pattern for woollens" , "Pattern on knitwear" , "Lozenge-shaped design" , "Lozenge-patterned sock" , "Old Scottish county; part name of a W Country football team" .)
