Why would nudity used in a piece of work?

Wait, part yapok? I'm not sure I want to know about the circumstances that led to that.

Number one, Mix-and-Match Critters are cool IMO. Number two, that was a joke.

On this site, it can sometimes be hard to tell. Even with the smiley.

What if a character was human but has changed:

• Came back wrong

• Blue-and-Orange Morality: with superpowers, becoming a cyborg, becoming a religious figure nudity taboos go out the window

• Freak Lab Accident

• Humanoid Abomination

• The character will Ascend to a Higher Plane of Existence

In the real world, everyone is born naked. And unless someone creates a way to permanently attach garments to a person's body, it's impossible to remain clothed.

In a fictional world, you can create places, situations, and reasons in which characters can/should be naked. For example, you might create a "first day of spring" festival in which people shed their winter clothes. Is this a popular trend or a dying custom? Is it becoming commercialized? Can only adults attend or participate? At the festival, are there different expectations for men and women?
