Evidently curvaceous heroine (4,2,3)

I believe the answer is:

joan of arc

I'm a little stuck... Click here to teach me more about this clue!

'heroine' is the definition.
(I have seen 'French heroine ' mean 'joan of arc' so perhaps 'heroine' could also mean 'joan of arc')

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for joan of arc that I've seen before include "She was known as the Maid of Orleans" , "Orleans girl" , "national heroine" , "burning visionary?" , "French heroine" .)

I've seen this clue in the Evening Standard.
