Her tights and panties

Renee was able to at least cover her bra with the shirt, bit then she noticed the breeze between her legs. She looked down and saw her bare legs and figured that was the source. Dismissing the breeze, and unaware she had no panties, she emerged from the restroom, not exactly caring about how she looked.

If she stared closer at how her shirt fit, she would notice the circular scorch marks on her bra were showing through, creating an illusion of showing her areolas. She went back to the cafeteria, a little embarrassed, but still confident she was covered. She took another tray and ordered her food. She sat down at a table and began eating. Most students were done and were hanging out or playing on the fields outside. She ate her meal in peace until it came time for her next class.
