From Victorian era curiosities to early 20th century equestrian and motorcycle wear to rare WW2 era items - Black Sign garments are beautifully constructed, with a shared identity and aesthetic cohesion running through the collection to a degree we rarely see in brands focusing on reproductions & recreations.

This is Black Sign's take on the classic and iconic USN chambray work shirt, a style so successful and prolific most don't even process they're looking at one. As close as one can come to the platonic ideal of a work shirt, it features a relaxed fit with solid construction, a comfortable fit, and two surprisingly spacious chest pockets.

Featuring a roomy and comfortable fit through the body, with an extended torso and curved hem for easy tucking in. Lightweight and breathable, it's the kind of staple piece that you can wear all year long, laying over or under it as necessary.

It's made from a handsome 100% cotton chambray with an irregular and slightly slubby surface texture. Crisp and breathable, it will soften over time from wear and washing, fading slightly too. It all closes up with urea buttons, a nod to the originals, with fun additional details, like selvedge side gussets and contrasting stitching throughout.

True to size. Wash cold and hang dry.
