Unattractive and plain, I go into salon finally for makeover (2,3,8)
I believe the answer is:
no oil painting
'unattractive' is the definition.
(I've seen this before)
'and plain i go into salon finally for makeover' is the wordplay.
I cannot really see how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
an anagram of 'plain' is 'lpain' which is located in the answer.
'i' is within the answer.
'go' could be 'ting' (tinging is a kind of going) and 'ting' is present in the answer.
The remaining letters 'oo' 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).
Can you help me to learn more?
(Other definitions for no oil painting that I've seen before include "that's inferior on the face of it" , "Somewhat unattractive" , "Portrait in water colours" , "plain" , "description of watercolour?" .)
