God dressing priest in short stockings (6)
I believe the answer is:
helios
'god' is the definition.
(Helios is an example)
'dressing priest in short stockings' is the wordplay.
'dressing' is an insertion indicator (inserted letters are dressed or clad in others).
'priest' becomes 'eli' (biblical figure).
'in short' means to remove the last letter.
'stockings' becomes 'hose' (I've seen this before).
'hose' with its last letter taken away is 'hos'.
'eli' inserted within 'hos' is 'HELIOS'.
(Another definition for helios that I've seen is " God of the sun in Greek mythology".)
