The OG-107 poplin shirt, designed to evoke the look of U.S. Navy advisors during the Vietnam War.

Based on the actual lightweight poplin shirts sold at PXs (military base stores) at the time, this shirt features a replica “MACV NAVAL FORCES” patch to recreate the U.S. Navy advisor style. While the shirt itself is authentic, the embroidery and patch are retrofitted replicas.

Unlike the standard OG-107 utility shirts made of cotton satin, this private-purchase item is crafted from lightweight cotton poplin fabric.

The lightweight, highly breathable poplin fabric is well-suited to Vietnam’s hot and humid climate, evoking the style of clothing that servicemen purchased at PXs and other locations in search of comfort. Its appeal lies in the light, airy feel of the fabric—a hallmark of private-purchase items distinct from standard issue—and its simple two-pocket design.Furthermore, this particular piece has been customized with short sleeves, giving it a look reminiscent of how servicemen dressed in tropical regions during the Vietnam War.

The standout feature is the vivid blue “U.S. NAVAL FORCES VIETNAM” patch attached to the left sleeve.

During the Vietnam War, the U.S. Navy was deeply involved not only in operations at sea but also in riverine operations centered on the South Vietnamese coastline and the Mekong Delta. Particularly in the late 1960s, it undertook important missions distinct from land-based combat, such as operations using river patrol boats and providing training and advice to the South Vietnamese Navy.

MACV (Military Assistance Command, Vietnam) was the command that oversaw U.S. military activities during the Vietnam War, and Navy advisors were also involved in providing support and operational guidance to the South Vietnamese military.

This shirt is a custom item designed to recreate the look of U.S. Navy advisors during the Vietnam War era.

The chest features black embroidery reading “SMITH” and “U.S. NAVY.”

Additionally, black oak leaf rank insignia—representing the rank of U.S. Navy Lieutenant Commander—are embroidered on both sides of the collar. Another key feature is that all insignia, with the exception of the patches, are embroidered directly onto the shirt itself.

Unlike typical custom shirts that simply feature a row of patches, this piece achieves a truly authentic look by seamlessly integrating the black embroidery with the olive green fabric. The name on the chest, the “U.S. NAVY” inscription, the rank insignia on the collar, and the colorful Navy patch on the left sleeve—

The combination of these details creates a unique presence characteristic of an Advisor shirt from the Vietnam War era.

While the base shirt is an authentic piece from that era, the “MACV NAVAL FORCES” patch on the left sleeve is a replica; this is not an original item featuring the period patch.

Furthermore, this does not prove that it was worn by a specific soldier at the time; it is strictly a reproduction designed to evoke the style of a Navy advisor’s uniform. Nevertheless, the combination of the fabric texture and signs of aging found on an authentic PX shirt, along with details inspired by the military fashion of that era, gives it a charm distinct from that of a brand-new replica.

Size: LARGE.
