'up because he's this' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

'bachelor with fair feature to smarten' is the wordplay.
'bachelor' becomes 'B' (abbreviation e.g. BA=Bachelor of Arts).
'with' is a charade indicator (letters next to each other).
'fair feature' becomes 'ride' (I've seen this in another clue).
'to smarten' becomes 'groom' (I've seen this before).
'b'+'ride'+'groom'='BRIDEGROOM'
