All the way

Jessica turned back to peruse Frankenstein. She got to the scenes of the monster traipsing across the mountains when the teacher called out to her in a gasp.

"Ms. Lutz!!" the teacher shrieked, "where are your clothes?!!"

Jessica looked down to see what the teacher was talking about when she saw her naked body and turned ghostly pale. She could see her boobs, her stomach puffing out a little from her sitting down and the rolls around her bellybutton, her lightly-shaven pussy, and even her bare feet as she wiggled her toes a little.

Turning back, she saw the 50's girl barely concealing a giggle with her hands.

"She did it!" Jessica pointed at the girl, "she took everything!"

Jessica stood up and turned back, walking to the girl's desk to try to see where the girl hid her clothes. She looked outside the window, however, and saw familiar swatches of yellow and pink fabric. All her clothes were stuck in the branches of a tree outside! Worse still, she could see her backpack stuck up there right along with them. Full of dread, she turned to her own desk to confirm that, indeed, none of her belongings except her Frankenstein book were there.

Knowing that everything separating her from being an animal was now outside, Jessica broke out in a sprint outside the classroom, yanking open the door as her brain short circuited and she got tunnel vision.
