Mirror Mirror in the Hall

How to get 'double' the space? Mirror-doors on Wardrobes, for example. We got ourselves a 3 meter long Pax Wardrobe in Ikea in expectation of the move, it's gonna go in the Entrance/Hallway in our tiny attic. It leaves us with a 60cm passage, not much, but the mirrored doors will hopefully help to make it feel less claustrophobic. Not going for an 80s look, just illusion of more space.
Booked the van for the move, it's all happening now!
