Affectedly refined or respectable (7)
I believe the answer is:
genteel
I believe this clue is a double definition.
'affectedly refined' is the first definition.
(I've seen this before)
'respectable' is the second definition.
(genteel means respectable or polished)
(Other definitions for genteel that I've seen before include "Well mannered" , "Mannerly" , "Terribly polite" , "Exaggeratedly polite" , "Affectedly refined or respectable" .)
