What is hiding in plain sight meaning?

Hiding in plain sight means to conceal oneself or something gradually in plain view so that it is not easily noticeable or out of place. It is a technique often used in espionage, camouflage, or disguise by blending in with the surroundings, acting as if nothing is unusual. It is a means of avoiding detection, as the most effective way to keep a secret is to keep it in plain sight, where others do not recognize it as such. It is also used metaphorically where something is so visible or present that it goes unnoticed or disregarded.
