The St. Louis Shirt from Post O’Alls is based on a simple two-pocket chambray shirt originally issued to firefighters in St. Louis, Missouri during the 1930s. This version has been carefully refined using a vintage example owned by designer Takeshi Ohfuchi for over forty years, preserving the original spirit while sharpening the details and proportions for modern wear. Cut from a soft grey cotton flannel plaid, the shirt balances warmth with an easy, everyday feel. Classic work shirt elements anchor the design, including a chin strap at the collar, a pen slot at the left chest pocket, and gussets at both sides of the hem. It’s a straightforward, well-studied piece that works as a light overshirt or worn on its own, embodying the kind of timeless utility Post O’Alls has been perfecting for decades. 100% cotton flannel plaid fabric 1930s St. Louis firefighter shirt reference Two chest pockets Chin strap at collar Pen slot at left chest pocket Gusseted hem Pre-washed finish Tumble dried at low temperature Made in Japan Tag Size Chest Shoulder Length Sleeve S 23.2 17.7 29.1 22.4 M 24.8 18.5 29.5 23.2 L 26.4 19.3 29.9 23.6 XL 28 20.3 30.3 24 A variance of +/-.5" is within tolerance.
