Stockings only ordered by Poles (6)
I believe the answer is:
nylons
'stockings' is the definition.
(I've seen this before)
'only ordered by poles' is the wordplay.
'ordered' indicates anagramming the letters.
'by' is a charade indicator (letters next to each other).
'poles' becomes 'NS' (north and south poles).
'only' with letters rearranged gives 'nylo'.
'nylo'+'ns'='NYLONS'
(Other definitions for nylons that I've seen before include "Women's stockings made from a sheer material" , "Clothing" , "Thin tights" , "Hose" , "Women's stockings made of synthetic fibre" .)
