Fashion empty suit of an unassuming character (6)
I believe the answer is:
modest
'fashion empty suit of an unassuming character' is the definition.
I can't judge whether this defines the answer.
'fashion empty suit' is the wordplay.
'fashion' becomes 'mode' (synonyms).
'empty' means to remove the middle letters.
'suit' with its centre taken out is 'st'.
'mode'+'st'='MODEST'
Can you help me to learn more?
(Other definitions for modest that I've seen before include "Lacking vanity" , "Native of Vienna" , "Not vain or showy" , "Decorous" , "Having a humble opinion of oneself" .)
