Tights only woven in north and south (6)
I believe the answer is:
nylons
'tights' is the definition.
(I have seen 'Thin tights' mean 'nylons' so perhaps 'tights' could also mean 'nylons')
'only woven in north and south' is the wordplay.
'woven' indicates anagramming the letters.
'in' is an insertion indicator.
'north' becomes 'N' (synonyms).
'and' is a charade indicator (letters next to each other).
'south' becomes 'S' (synonyms).
'only' is an anagram of 'ylon'.
'n'+'s'='ns'
'ylon' placed within 'ns' is 'NYLONS'.
(Other definitions for nylons that I've seen before include "Stockings made of artificial material" , "Thin tights" , "Women's stockings made of synthetic fibre" , "Women's stockings made of synthetic material" , "Sheer stockings for women" .)
