Fashionable English stage worker lacking in refinement (9)
I believe the answer is:
inelegant
'lacking in refinement' is the definition.
(I've seen this before)
'fashionable english stage worker' is the wordplay.
'fashionable' becomes 'in' (similar in meaning).
'english' becomes 'e' (abbreviation).
'stage' becomes 'leg' (synonyms).
'worker' becomes 'ant' (worker is a type of ant).
'in'+'e'+'leg'+'ant'='INELEGANT'
(Other definitions for inelegant that I've seen before include "Lacking refinement" , "Ungraceful" , "stiff" , "not the cultivated sort" , "Awkward - graceless" .)
