Based on the details and design, this is from around the late 1940s. 【Size/Color】 - M - Length (from collar): 64cm Shoulder width (from shoulder seam to seam): 42cm Width (measured at armpits): 52cm Sleeve length (from shoulder seam): 55cm Sleeve + shoulder length (from center of neck to cuff): 75cm I (165cm/53kg, slender build) could wear this with a good fit, and the sleeve length was just right. Depending on your preference and how you wear it, I recommend it for people around ~165cm tall! The blue x red x white color scheme is rare and the balance is superb, giving a fresh impression. #WhatBlue? ← Check out blue items!! #WhatRed? ← Check out red items!! #WhatWhite? ← Check out white items!! 【Condition】 Repaired on the right shoulder as shown in image ①. Pin-hole sized damage on the hem, as indicated by the white arrow, which is not noticeable from a distance. Rough self-repairs on 4 buttonholes, the red arrow indicates the most noticeable one. Although it's misshapen, the old buttonholes are distorted due to the sewing machine's performance, which gives it character. One front button was missing, so I attached one from the sleeve, and then removed the other sleeve button to balance it out, and attached one I had on hand. I feel it looks better than the original balance, though I say so myself. 【Remarks】 From the outward-flared collar and long box silhouette, and the felled seam (yellow arrow) specifications, it's a transitional design with details from the 1940s and 1950s. SPORTCLAD, which JC Penney was selling, is popular but not often found. Furthermore, the old tag is complete and rarely seen. The pattern matching on the pockets is also excellent. The buttons are shell buttons, and only the top hole has black stitching, while the others are white, showing the meticulous craftsmanship of old items. It's compact, but there's no noticeable shrinkage, and it's a M size typical of the time when people were smaller. Smaller sizes and regular sizes are available, but a size that allows an adult male to wear it with a small, just-right fit is rare. It has the feel of a grunge-before-punk flannel shirt, and goes well with zip pants and slim-fit distressed denim. I'm also listing other store brands. #WhatSTR? Please check it out!
