👉 Preclothing is a type of clothing that is worn under another piece of clothing, often to cover the skin or to provide extra protection. This can be in the form of a shirt over pants, shorts underneath trousers, or even as a jacket over a sweater or coat. Preclothing can also refer to the process of transforming clothes into something else by adding additional layers or accessories such as hats, gloves, and scarves.
