Quite wealthy (4-2-2)
I believe the answer is:
well-to-do
'quite wealthy' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for well-to-do that I've seen before include "Rich; old towel (anag.)" , "Quite wealthy" , "'Prosperous, wealthy (4-2-2)'" , "Comfortably off" , "Fairly rich, prosperous" .)
