all skin and bones

Dangerously, visibly underweight

All skin and bones describes someone or something extremely thin, as if the body has no flesh—only skin stretched over the skeleton.

The phrase emphasizes alarming or unhealthy thinness: After his illness, he was all skin and bones.

Sometimes shortened to skin and bones or inverted as nothing but skin and bones.
