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

'dainty' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for mignon that I've seen before include "girl of Goethe's" , "in Goethe's poem" , "Dainty (from French)" , "Small and dainty" .)

I've seen this clue in the Evening Standard.
