She has half a mind to appear in jeans, perhaps (7)
I believe the answer is:
jasmine
'she' is the definition.
'half a mind to appear in jeans perhaps' is the wordplay.
'half a' means to take half the letters.
'to appear in' indicates putting letters inside.
'perhaps' is an anagram indicator.
'mind' with half the letters taken is 'mi'.
'jeans' anagrammed gives 'jasne'.
'mi' inserted into 'jasne' is 'JASMINE'.
'has' acts as a link.
(Other definitions for jasmine that I've seen before include "Sweet-smelling shrub" , "Shrub with fragrant yellow or white flowers" , "Fragrant flower" , "Fragrant shrub used to flavour tea" , "Plant" .)
