This is a classic, genuine U.S. military "Baker Shirt." This is a government-issued item from the mid-1970s (made in 1976), a rare 100% cotton satin fabric version from before the shift to polyester blends (OG-507). This piece has the characteristic horizontal unevenness of cotton satin from this era, which appears with wear (similar to back satin), and the button wear is very cool. The deep olive color, a vintage characteristic, is irresistible. It's in a plain state with the patches removed, so it can be worn with any style without hesitation. It's a versatile piece that can be worn as a shirt or, at this time of year, as an inner layer. 【Details】 • Era: 1970s (made in 1976) • Material: 100% COTTON (cotton satin) • Color: Olive Green (OG-107) • Specifications: Genuine U.S. military issue (DSA100-76-C marking) 【Size】 Marked Size: 14 1/2 × 33 (Fits like a Japanese size S to M, a neat fit) Actual measurements are as follows: • Shoulder width: 44cm • Body width: 50cm • Length: 74cm • Sleeve length: 63cm ※ Please note that there may be slight variations due to amateur measurements. 【Condition】 In excellent condition for a vintage item from about 50 years ago, it's close to a "mint condition" piece with the color well-preserved.
