Your mind is already getting a little foggy as you try to pull yourself away from the mirror, and yet the mirror seems to have some sort of hypnotic power over you. You can feel yourself struggling to pull back, but only manage to take a step back. Your mind has a brief out-of-body experience, causing you to be disoriented, and you nearly fall over.
You managed to pull away from the mirror briefly to regain your bearings. However, you find it extremely difficult to take a deep breath. It seems that mirror's altered your clothes while you were disoriented, as you feel the tightening of a corset against your rib cage. You look down to see yourself decked in a purple Victorian-styled gown, with the blue corset hugging your chest tightly. The gown's skirt has multiple frills, with a petticoat underneath, nearly limiting your movement as your feet also decked in heels that you can't see at the moment. The skirt's volume is more prominent in the back, with a weight train dragging a little on the floor. You check up to see some of the fabric going across your shoulders and over the corset, still exposing a little of your cleavage and shoulders, as you have an old pendant hanging from your neck. Finally, bringing up your opera-length gloved hands, you reach up to feel a little feathered pin on one side of your hair...
This mirror's power has changed your clothes to fit with the bedroom's decor, it seems, and you find yourself visibly worried that the mirror might make the situation even worse. You have GOT to get out of here as soon as possible.
