Polished English cricket side followed by six-footer (7)
I believe the answer is:
elegant
'polished' is the definition.
(thesaurus)
'english cricket side followed by six-footer' is the wordplay.
'english' becomes 'e' (abbreviation).
'cricket side' becomes 'leg' (I've seen this before).
'followed by' says to put letters next to each other.
'six footer' becomes 'ant' (an ant has six feet).
'e'+'leg'+'ant'='ELEGANT'
(Other definitions for elegant that I've seen before include "Ingenious" , "A gentle way to be stylish" , "Well-turned" , "Tasteful and refined in appearance" , "Neat leg? (anag)" .)
