The CPO Shirt channels vintage naval officer aesthetics in its overshirt design, elegantly adorned with replica BDU buttons and a crossed back yoke. Crafted from gauzy mid-weight cotton, the fabric's consistent sashiko stitching imparts a tactile loftiness.
Inspired by a double-faced Japanese sashiko fabric 3sixteen introduced in 2016, the brand pursued a softer, better-draping iteration suited for base layers. Collaborating with an Indian mill, they reimagined the fabric with a looser weave and increased loft. The sashiko pattern within mimics the robust threads seen in intricate repairs on old Japanese workwear. The black overdyed version promises lasting depth, occasionally revealing hints of grayish-blue as the indigo layer below surfaces through wear.
The cut features a slight slim fit and stays true to standard sizing. If you usually wear a size M in 3sixteen shirts or other American brands, you'll find a suitable fit with this shirt in size M. However, as always, we recommend consulting our size chart for the perfect fit.
Founded in LA by Johan Lam and Andrew Chen over a decade ago, 3sixteen's philosophy is evident in pieces they've developed since 2008: shirts, jackets, basics and accessories all take cues in form and function from their jeans. Fabrics and trims are always chosen for their capacity to develop character with time. 3sixteen aim is that, with diligent wear, the customers are rewarded with something well-aged, never “old.”
