Work out why the swimsuit looks so good on (6)
I believe the answer is:
figure
'work out' is the definition.
(I've seen this before)
'why the swimsuit looks so good on' is the wordplay.
I cannot quite see how this works, but
'good' could be 'g' (abbreviation) and 'g' is located in the answer.
'on' could be 're' ('on' can be mean 'with reference to') and 're' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for figure that I've seen before include "Consider" , "movement by skater" , "Shape; number" , "Person's bodily shape" , "Body shape" .)
