Stylish English stage worker (7)
I believe the answer is:
elegant
'stylish' is the definition.
(thesaurus)
'english stage worker' is the wordplay.
'english' becomes 'e' (abbreviation).
'stage' becomes 'leg' ('leg' can be a synonym of 'stage').
'worker' becomes 'ant' (worker is a type of ant).
'e'+'leg'+'ant'='ELEGANT'
(Other definitions for elegant that I've seen before include "Attractive and graceful or stylish" , "Polished" , "A gentle way to be stylish" , "Stylish in appearance, a gentle kind" , "Teen gal (anag.)" .)
