Figure of girl finally exuding sex appeal (5)

Ross

I believe the answer is:

digit

'figure' is the definition.
(thesaurus)

'girl finally exuding sex appeal' is the wordplay.
'girl' becomes 'di'.
'finally' indicates one should take the final letters.
'sex appeal' becomes 'it'.
The final letter of 'exuding' is 'g'.
'di'+'g'+'it'='DIGIT'

'of' is the link.

(Other definitions for digit that I've seen before include "using 0 or 1 for example" , "Finger, thumb or toe" , "Like It?" , "Need a bit of a hand" , "A character" .)

I've seen this clue in The Times.
