Different countries have different climatic conditions, and people dress accordingly. In countries with hot weather, people wear lighter clothes made of natural fibers such as cotton, while in colder climates, people wear heavier clothes made of synthetic materials or wool. People also dress differently according to their cultural traditions. In some cultures, women cover their heads with a scarf or veil, while in others, men wear turbans. So there are a variety of reasons why people dress differently in different parts of the world – it all depends on the climate and the culture.
