Light, crisp, and effortlessly refined - the RGT Oxford Shirt returns in an elevated 4oz Japanese poplin. Crafted from a premium 70% cotton, 30% nylon blend, this fabric offers a smooth, breathable feel with a subtle structure that drapes just right. A single chest pocket keeps things classic, while the box pleat at the back yoke ensures ease of movement. Urea catseye buttons, sourced from Japan, add a refined touch, and the natural locker loop brings both function and vintage charm. Thoughtfully sewn in Los Angeles, this is an Oxford that balances tradition with a modern sensibility. 4oz Japanese Poplin 70% Cotton, 30% Nylon Single chest pocket Double-needle chainstitch seams Box pleats at the back yoke Urea cat's eye buttons made in Japan Natural herringbone locker loop  Sewn in Los Angeles table { width: 100%; border-collapse: collapse; } th, td { border: 1px solid black; padding: 8px; text-align: center; } th { background-color: #f2f2f2; } Tag Size Chest Shoulder Front Length Sleeve Length S 20.75 16.75 27 25.25 M 21.75 17.25 27.5 25.75 L 23 17.75 28.5 26.25 XL 24.25 18.25 29.5 26.75 XXL 25.75 19.25 30 27.25 XXXL 27 20 30.5 27.5 A variance of +/-.5" is to be expected.  Fit Notes: Shop owner Tommy has sized up once to a large in this. This seemed to fit a little more tailored and traditional, like we're used to from RGT. This would be the size he would purchase as well. It was perfect as an oxford style second layer, vs a final layer. This is one we 100% recommend sizing up once on.
