Zephyr is standing on a glass floor looking down as Petra performs a handstand directly beneath him on the other side of the glass. Petra is wearing a loose T-shirt. What does Zephyr see in regard to Petra's T-shirt?

Provide a very short response.
Zephyr sees Petra's T-shirt hanging down towards the ground because of gravity. Since Petra is upside down, her T-shirt, which is not tightly fitted, will fall away from her body towards the earth, revealing her torso unless the T-shirt is tucked in or in some other way secured to her body. Zephyr's viewpoint from above allows him to observe this effect as the T-shirt droops downwards due to gravity acting on it.
