Suit in church perhaps moved by sad tunes (6,4)
I believe the answer is:
sunday best
'suit in church' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'moved by sad tunes' is the wordplay.
'moved' indicates anagramming the letters.
'by'+'sad'+'tunes'='bysadtunes'
'bysadtunes' anagrammed gives 'SUNDAY BEST'.
'perhaps' is the link.
Can you help me to learn more?
(Other definitions for sunday best that I've seen before include "Clothes kept for special occasions" , "Smartest clothes" , "smartest suit, say" , "clothes for the day after" , "One's finest outfit" .)
