Why is wearing only a diaper out in public considered indecency dressed?

Wearing only a diaper in public is generally considered indecent because it deviates from societal norms regarding appropriate attire. Public decency laws and cultural standards typically require individuals to wear clothing that covers their bodies in a manner deemed acceptable. A diaper, while functional, is not regarded as sufficient clothing for public settings, leading to perceptions of embarrassment or discomfort for both the wearer and those around them. This behavior often raises concerns about hygiene and social appropriateness.
