Sunglasses suit husband rather than papa (6)
I believe the answer is:
shades
'sunglasses' is the definition.
(synonyms)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for shades that I've seen before include "Slight differences between colours" , "Cool sunglasses or archaic ghosts" , "Nuances" , "disguise, sometimes" , "Ghosts or slang sunglasses" .)
