Best substitute for shaving soap (5)
I believe the answer is:
cream
This could be a double definition.
'best substitute for shaving' is the first definition.
'cream' can be an answer for 'best' (both can mean the elite). I am unsure of the 'substitute for shaving' bit.
'soap' is the second definition.

Can you help me to learn more?
(Other definitions for cream that I've seen before include "treat for cat?" , "It rises to the top, the best" , "Butterfat part of milk" , "An off-white shade" , "The best part -of the crop" .)
