Not entirely good, and yet excellent! (5)

I believe the answer is:

dandy

'excellent' is the definition.
(thesaurus)

'not entirely good and yet' is the wordplay.
'not entirely' indicates a hidden word.
'DANDY' is hidden in the letters of 'good and yet'.

(Other definitions for dandy that I've seen before include "Playboy" , "Fop; excellent (US)" , "Fashionable fellow" , "Stylish dresser" , "one of stylish ways" .)

I've seen this clue in The Times.
