Even though a dashiki shirt, just like a T-shirt is a casual summer style option but this doesn’t mean you can’t wear it in winter or fall. It’s better to give it a break when it’s too cold, but you can wear it when the temperature is moderately cool. When temperature takes a dip layering is your option. You can layer a denim jacket, a casual blazer, or a puffer vest to stay warm when it gets cool.
