Vintage J. Crew Heavyweight Flannel Work Shirt in great used condition. Size: Slim M Color: Dark Hinting Green This customer favorite is inspired by vintage workwear. - It's made from a soft brushed chamois fabric that feels broken-in, in a heavier-weight 10.3-ounce cotton—perfect as an outer or under layer. This casual-but-still-polished workshirt is pretty much perfect for fall (and winter, and early spring. . .)
