We made the CPO Button Down as a modern heirloom, drawing on the utility and structure of naval overshirts once issued to Chief Petty Officers. Crafted in heavyweight cotton twill, it brings density and durability without sacrificing comfort, softening as it’s worn in. A classic button-front anchors the piece, with dual chest pockets that add both function and symmetry.

Layer it over a tee, wear it buttoned on its own, or throw it beneath a jacket, this shirt adapts across seasons and settings. It’s a piece of uniform heritage, reimagined for everyday life, with the strength of history stitched into every seam.

The HA-107 Pant was designed as a foundation piece inspired by the iconic OG107 military trouser, the HA107 Pant is reimagined with Heirloom Amalgam's signature approach... sharp enough to carry polish, relaxed enough to live in. 

Made from sturdy, breathable cotton twill, it holds its structure while easing into a softer drape over time. The straight fit offers balance through the leg, creating a clean line that flatters without feeling restrictive.

From weekday commutes to weekend escapes, the HA-107 adapts with ease. Pair it with a button-down for structure, or a soft tee for casual movement. Built to last, meant to wear often, it’s a pant that grounds your wardrobe in confidence.

Inspired by vintage military styles, the CPO Shacket is crafted from premium cotton stretch denim designed to last.

Subtle western influences, from breast pockets to back yoke, bring character to its classic silhouette.

Finished with mother-of-pearl buttons and tailored details, it’s a versatile staple for year-round wear.  Equally suited for transitional weather or as a foundational layering piece in cooler months

Layer it effortlessly over the Dionysus Dress, the Le Mans Racer-back Tee, or the Franklin Henley.

We designed the Ursula Short to blend polish and ease, so you never have to choose between the two. The high-waist fit shapes cleanly at the top, while the relaxed leg lets you move freely. Crafted from breathable cotton, it’s light enough for warm days but structured enough to feel refined.

Style it with a tucked tee for everyday ease, or pair it with a blouse for evenings out. With balance in every detail, the Ursula Short is built for days that move between leisure and intent, sharp when you need it, soft when you want it.
