Look for clues

The costume had a plaque that she didn't fully read before, maybe there are instructions on removing this thing?

"Something is seriously wrong with this store" she thought, as she wandered that labyrinth of the building.

On one hand, she was admiring the multitude of rich costumes, seemingly never-ending variety, some costumes were similar, but no two were the same.

On the other, she was traversing the store wearing a translucent sheet of fabric, that also made her invisible! The store also did not seem to end!

Store more and more looked like an actual labyrinth - and she was slowly losing hope of ever finding the place she was looking for ... or the woman for that matter.

She was wrong, however. The store was finite. She recognized the Rusalka costume and was sure the hallway to the right was where her ghost costume originated. At the same time, she was about to turn right, she heard a person walking on the left side.
