Stretchy hose only sprayed neighbours' borders (6)
I believe the answer is:
nylons
'stretchy hose' is the definition.
(tights made of nylon)
'only sprayed neighbours' borders' is the wordplay.
'sprayed' indicates an anagram (I've seen this in other clues).
'borders' suggests removing the centre (only the edge or border letters remain).
'neighbours' with its centre taken out is 'ns'.
'only' anagrammed gives 'nylo'.
'nylo'+'ns'='NYLONS'
(Other definitions for nylons that I've seen before include "Thin tights" , "Silk-like stockings" , "Women's stockings made of synthetic fibre" , "Clothing" , "Women's stockings made from a sheer material" .)
