Bodysuit

An increasingly more common form of transformation. Typically. Skin colored spandex body suit that covers a person’s entire body. The end result is them looking like someone else.

In real life body suits exist and are used by people to look like anime girls or Barbie dolls. The effect usually is reminiscent of the uncanny valley.

In fiction these transformations are usually seamless with the wearer looking exactly like who they are supposed to be. In science fiction examples the body suit will have almost no visible hints that it’s not real.

Many stories involve a person buying a bodysuit online. In others the person may have a gun that can turn people into skin suits. Typically the ray gun will hit the victim turning them into a crumpled skin colored suit of fabric within the victim’s clothes. Stories will result in cases of mistaken identity. Sometimes this bodysuit change can be reversed by zipping up the body suit without anyone inside it, thus turning the victim back to normal. But a lot of erotica skips this in favor of the change is permanent and that person is effectively dead.

A typical bodysuit story will end with a zipper is stuck moment causing the wearer to be stuck in their new form.

In some cases a magical effect might be on the suit which allows for the wearer to feel every sensation as if the suit is their real body. In some cases this will result in the wearer being able to experience the opposite gender’s anatomy.
