You know, right hand twill and left hand twill are both great twills. Even a broken twill is a much-welcomed twill, all twills considered. But when you want a little bit o’ fish in your workwear (because everyone describes it like that), herringbone twill is the twill you want.

And Iron Heart gives the indigo pescatarian what they totally asked for with their Indigo Heavy Herringbone Workshirt. Featuring a single patch pocket and tonal stitching throughout, they’ve made it simple enough for the fabric to shine through to the surface. You’ll also find black cateye buttons, selvedge gussets with chainstitch runoff and a soft, rinsed feel from the get-go.

Available at Self Edge for $345.
