Flushed, as cheeks (4)
I believe the answer is:
rosy
'flushed as cheeks' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rosy that I've seen before include "Blooming - hopeful" , "lady" , "Promising; hopeful" , "Hopeful; blushing" , "Healthy-looking" .)
