National Flannel Day – A day to wear your flannels! Celebrated annually on February 10 by wearing flannel.
The words “flannel” and “plaid” are often used interchangeably, but they are referring to two different things. Flannel is a material or fabric, not a pattern. In contrast, plaid is a pattern.
Check this image, I used a photo of me wearing my red flannel shirt and Photo Lab app that lets you put them on various backgrounds.
Usually you think of flannel with outdoor wear. But they can be used for common causal wear too. I have a red and green one and I like wearing them. Flannel is usually warm clothes, great to wear in cool weather.
I am not sure when or how this day got started.
