Why is "Battle Dress" trending?

Wikipedia Overview

A combat uniform, also called a field uniform, battledress, or military fatigues, is a casual uniform used by military, police, fire, and other public uniformed services for everyday fieldwork and duty, as opposed to dress uniforms for formal functions and parades. It generally consists of a jacket, trousers, and shirt or T-shirt, all cut to be looser and more comfortable than more formal uniforms. Combat uniform designs vary by regiment or service branch. Uniform fabrics often come in camouflage, disruptive patterns, or otherwise olive drab, brown, or khaki monochrome, to approximate the background and make the soldier less conspicuous in the field. In Western dress codes, field uniforms are considered equivalent to civilian casual wear, less formal than service dress uniforms, which are generally for office or staff use, as well as mess dress uniforms and full dress uniforms.
