Because many layers of cotton clothes trap a more amount of air in between them, as we know that air is a poor conductor of heat it do not allow the body's heat to go outside and as a result it keeps us warm.

Answer:
During winters, we prefer wearing more layers of clothing than just one thick piece of clothing because air gets trapped in between the various clothing layers. Being a poor conductor of heat, air prevents heat loss from our body. Hence, layers of clothing keep us warmer than a single layer.
