Costume Stand

She hesitated, but that could honestly be another customer, she certainly didn't want to face now!

Success! She has found the empty space her costume occupied!

She took a look at the tablet. It read:

Wandering Ghost

Not bound to any place, in particular, this kind of ghost is free to wander around the world freely, without any obstruction. It can be however summoned by calling its name or exorcised if it's causing mischief. Possesses limited ability to interact with the physical world.

Costume use instructions

1. The costume can be only removed in set intervals: a second after a minute. a minute after an hour. An hour after a day. A day after a week. A week after a month. A month after a year. A year after a decade, A decade after a century. A century after the millennium.
2. Costume grants the person the usual attributes of ghosts and poltergeists. Specific properties will depend on the wearers attunement to the occult, and reality anchoring.
3. As wearer becomes removed from the earthly plane of existence, reality adjustments might occur to deal with the occult phenomena.
4. Wearer might experience memory and identity crisis, stronger the longer it remains in costume.

"What? I'm a ghost now?!" was the first thought of our heroine.
"Memory loss? Identity crisis? The fuck? Better remove this thing ASAP", was the following thought. Shortly succeeded by "How long have I been wondering this labyrinth?"

She obviously missed a second after the first minute. So the next attempt must be made a minute after an hour. But how much time has passed?

She couldn't check her phone, and the store was not exactly full of clocks either.
