Stylish European support worker (7)
I believe the answer is:
elegant
'stylish' is the definition.
(thesaurus)
'european support worker' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'support' becomes 'leg' (leg is a kind of support**).
'worker' becomes 'ant' (worker is a type of ant).
'e'+'leg'+'ant'='ELEGANT'
(Other definitions for elegant that I've seen before include "Chic; smart" , "Well-dressed" , "Tasteful and refined in appearance" , "A gentle way to be stylish" , "Stylish in appearance, a gentle kind" .)
