Why do we wear certain clothing in certain seasons? In the winter, we wear heavier clothes to stay warm, while in the summer, we wear lighter clothes to stay cool. In the spring and summer, the days are longer and the sun is brighter, so we tend to gravitate towards lighter colors that reflect the sunlight. In the fall and winter, the days are shorter and the sun is less bright, so we tend to gravitate towards darker colors that absorb more heat. But I think it is more than these practicalities
