Immediately taking on economy, without any fancy trimmings (8-3)

I believe the answer is:

straight-cut

'without any fancy trimmings' is the definition.

'immediately taking on economy' is the wordplay.
'immediately' becomes 'straight' (as in straight away).
'taking on' says to put letters next to each other.
'economy' becomes 'cut' (I've seen this in other clues).
'straight'+'cut'='STRAIGHT-CUT'

I've seen this clue in The Independent.
