TCB Jeans S40's This denim jacket is based on the 1940s wartime model. This model faithfully reproduces the design of the 1st type seen during the wartime period of the 1940s, with details such as the front box pleats, a single pocket without a flap, the center seam (T-back) on the back, and a cinch back. The fabric is TCB's signature uneven denim, and as of now, there is still a lot of color remaining, so you can enjoy the aging process through wear and washing. This is a piece that still has plenty of room to grow. Marked size: 40 [Actual size (flat measurement, cm)] Shoulder width: 46 Body width: 49 Length: 63 Sleeve length: 63 *Please note that there may be slight errors due to amateur measurements. For those who are around 165-175cm tall and of average build, it's the perfect size to wear over a T-shirt or a thin sweatshirt. With the short length and compact silhouette characteristic of 1940s work jackets, you can enjoy the balance of the time, which is different from modern oversized styles.
