Breast implant mimic to be most affordable (8)
I believe the answer is:
cheapest
'be most affordable' is the definition.
I can't tell whether this definition defines the answer.
'breast implant mimic' is the wordplay.
I cannot really understand how this works, but
'mimic' could be 'ape' (ape can mean to copy or imitate) and 'ape' is found within the answer.
The remaining letters 'chest' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for cheapest that I've seen before include "Most economical" , "Lowest in price" , "Most vile" , "Of the poorest quality" , "It's most shameful" .)
