Get depressed around midnight in night attire (3,4)

I believe the answer is:

bed gown

'night attire' is the definition.

'get depressed around midnight' is the wordplay.
'get' becomes 'be' ('get' can mean 'come to be').
'depressed' becomes 'down' (synonyms).
'around' indicates putting letters inside.
'midnight' becomes 'g' (the middle letter in 'night').
'down' placed around 'g' is 'dgown'.
'be'+'dgown'='BED GOWN'

'in' is the link.

I've seen this clue in The Guardian.
