Cheeky but attractive feature (6)
I believe the answer is:
dimple
'cheeky but attractive feature' is the definition.
The answer and definition can be both body parts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for dimple that I've seen before include "Slight depression (in the skin)" , "Natural dent in skin" , "Attractive facila indentation" , "Shallow depression" , "Little dent in flesh" .)
