Why is "Dead-character costume" trending?

Wikipedia Overview

A dead-character costume is a set of stage clothes specially designed or modified for actors portraying characters killed on screen or on stage. They are used to depict gunshot or stab wounds, damage and the visual aftermath of violence, and are usually prepared by integrating special-effect devices such as blood squibs or prosthetics. Despite the character being "killed" only once on-screen, multiple identical costumes are typically used for several takes and scenes to ensure consistency and continuity, as the irreversible damage caused by squibs or blood effects limit their reusability. They are sent to separate costume racks and disposed of afterwards, unlike other clothing articles that may return to the costume shop. These costumes serve as a metaphorical canvas to portray injury and death without the need for digital post-production effects.
