The U.S.N. WOOL BLUE FLANNEL SHIRT / U.S.S. BROOKLYN is made from a wool twill and finished with period-correct U.S.N. urea anchor buttons. Originally issued to Chief Petty Officers in the early 1940s, this single-pocket shirt features Liberty Cuffs, which are embroidered patches sewn on the inside of the sleeves. It also includes an arched pocket flap and cuffs made from matching parts, reflecting wartime efforts to simplify production.

Liberty Cuffs are embroidered patches sewn on the inside of the sleeves of the CPO shirt, a distinctive feature that allowed sailors to express personal style within the Navy’s strict discipline. Though officially against regulations, sailors commonly rolled up their sleeves to display these cuffs while on shore leave. This practice originated in the early 1900s, particularly among sailors of the Asian fleet, and by World War II had become an established naval tradition.

These embroidered cuffs were often found on the Blue Dress Jumper, the wool “sailor suit” issued to non-commissioned officers. Popular motifs included dragons and mermaids, with specific designs tied to the wearer’s duties. For example, submarine crews typically wore dolphin patches, while aviation pilots chose bird designs.

Near naval bases in the United States, shops called Rocker’s Clubs provided official services such as locker rentals and uniform alterations. These establishments also frequently installed Liberty Cuffs, supporting this unofficial but widely embraced naval tradition.

Once an open secret and a celebrated part of Navy culture, Liberty Cuffs saw a decline in use after the 1970s, when sailors were permitted to wear civilian clothes during shore leave.

The CPO shirt was introduced in the 1920s with a double-pocket design but switched to a single-pocket style during World War II, likely to streamline production. After the war, the double-pocket style returned in the late 1940s. Although the shirt was not officially part of the peacetime uniform, sailors could wear it with permission from senior officers, especially in cold weather. Over time, this rule became less rigid and more widely accepted.

Post–World War II, surplus CPO shirts spread to army-navy stores, where they found a new audience beyond the military. Outdoor enthusiasts and tradesmen gravitated toward the heavy wool overshirts. As their popularity spread, the term “CPO shirt” came to describe a wider category of civilian work shirts inspired by the Navy original. Many retained signature features such as flap chest pockets and the classic anchor-stamped buttons, preserving their maritime roots.

The U.S.S. Brooklyn operated along the chilly Atlantic coast and on escort missions to Casablanca, where dependable cold-weather gear was essential. Built at the Brooklyn Navy Yard and named after the New York borough, the ship participated in the opening ceremonies of both the 1939 New York World’s Fair and the 1940 Golden Gate International Exposition. The ship’s stencil remains simple, featuring only the vessel’s name and hull number, just as it appeared in service.
