Amanda's clothing moved away from the table and stood to my left. Her tennis shoes were visible but there were no legs rising up from her ankles to the mid-calf length dress. She walked around a bit, twirling around and making the dress hem rise up a little. She was having fun with her transparency.
I heard a book fall slam into the ground somewhere behind me. It must have been a few stacks over. Amanda's clothing stood still and dashed under the table. "I can't be seen like this, Joe. Do something!" she said quietly but in a disperate tone.
I looked under the table and could see into her blouse through the neck hole. I could see down to the dress including the white underwear she wore. It was a little dark inside, though as she didn't have any direct light shining on her. This would be hard to explain to anyone and would like require doing something to anyone who discovered her.
"Amanda, I wish your clothing to be invisible," I requested. Instantly, there was nothing to see under the table.
"Oh my..." Amanda's voice said as something brushed up against my leg. Then she said into my ear, "Thanks! This is helpful. Be right back!"
"Amanda?" I said with a hushed question. I looked around me and had no idea where she was.
