NEW COLLECTION AUTUMN-WINTER 22/23. This dark blue flannel shirt has a Button Down collar, which is considered the most common for sports and casual shirts. The tips of the collar are fastened with a button, which keeps them in one place, so the collar looks just as good with or without a tie. The 100% cotton material comes from the luxury Italian manufacturer Albini. The real pearl buttons are a beautiful accessory to the shirt. Most people associate flannel with heavy work shirts, but that hasn't been the case for a long time. Flannel is a trendy material that is now popular mainly among the younger generations. Flannel shirts are popular for the cooler seasons of fall and winter.
