Classic example of a period shirt from the 1930s, collarless with button holes at collar line for attaching collar too.
Shirts were often collarless in the 1930s because detachable collars were a common feature of men's fashion at the time. Detachable collars allowed men to maintain a crisp, clean look without frequently laundering the entire shirt, which was more labor-intensive in that era. This design also made it easy to replace worn or soiled collars, saving money and extending the life of the shirt. The practice was rooted in the late 19th and early 20th centuries but remained popular among certain classes and professions in the 1930s due to its practicality and the formal aesthetic it provided.
