Most good-looking worker, some very holy person too (10)

I believe the answer is:

handsomest

'most good-looking' is the definition.
(the most handsome)

'worker some very holy person too' is the wordplay.
'worker' becomes 'hand' (hand is a kind of worker).
'very holy person' becomes 'st' (saint).
'too' means one lot of letters go next to another.
'hand'+'some'+'st'='HANDSOMEST'

(Another definition for handsomest that I've seen is " Most striking".)

I've seen this clue in The Times.
