Why do people prefer to wear dull clothes in winter?

People often prefer to wear dull clothes in winter due to the season's subdued light and colder weather, which can influence mood and fashion choices. Dull colors, like grays, browns, and dark blues, tend to provide a more understated aesthetic that aligns with the somber atmosphere of winter. Additionally, these colors can be easier to mix and match, making them practical for layering. Lastly, darker tones are also less likely to show dirt and wear, which is a consideration during the slushy, messy winter months.
