Put on this costume

I stand like this for a few more seconds, staring frightened at my mother's body. Suddenly, I hear my aunt and nephew's voices from the hallway. Mom was supposed to meet them, but now her body had been turned into a costume. Then it's like I subconsciously know what to do.

I frightenedly pick up the suit from the floor. I find a hole in the back of the suit. Then I gently shove my foot inside the hole pulling my mother's leg over mine. Immediately the suit sticks to my leg and I feel a strange warmth. But I don't stop. I shove my other leg inside the suit, and then I put my hands in and pull my mother's face over hers. Then, I suddenly feel that the hole through which I got into this suit begins to tighten. And in a few seconds, I'm already fully dressed in the suit. I wanted to at least look in the mirror, but my aunt started calling my mother and I knew I had to go. I quickly put on my mother's clothes, which were on the floor, and headed out to meet the guests.
