Her figure can be so wrong? (4-6)
I believe the answer is:
pear-shaped
'so wrong?' is the definition.
The definition suggests an adjective which matches the answer.
'her figure' is the wordplay.
I cannot quite see how this works, but
'figure' could be 'shape' (synonyms) and 'shape' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'can be' acts as a link.
Can you help me to learn more?
(Other definitions for pear-shaped that I've seen before include "(Go) horribly wrong; like three Satie pieces" , "Fat at one end and thin at the other - all wrong!" , "With hips very wide compared to the upper body" , "Bottom-heavy: (gone) wrong" .)
