City displaying stylishness in the past (7)
I believe the answer is:
chicago
'city' is the definition.
(Chicago is an example)
'stylishness in the past' is the wordplay.
'stylishness' becomes 'chic' (synonyms).
'in the past' becomes 'ago' (synonyms).
'chic'+'ago'='CHICAGO'
'displaying' is the link.
(Other definitions for chicago that I've seen before include "Type of bridge" , "A Windy City in Illinois" , "1970s' John Kander/Fred Ebb musical" , "Musical (in Illinois?)" , "City on Lake Michigan" .)
