This item appears to be from around the 1970s, judging by the details and design. 【Size/Color】 - M - Length (from collar): 72cm Shoulder width (from shoulder seam to shoulder seam): 42cm Width (measured at the armpits): 50cm Sleeve length (from shoulder seam): 22cm Sleeve length (from center of neck to cuff): 43cm I (165cm/53kg, slim build) could wear this with a good look. It depends on your preference and how you wear it, but it's recommended for slim people up to around 170cm tall!!! The impression is navy with red. #WhatBlueIsThis? ← Check out navy items!!! #WhatRedIsThis? ← Check out red items!!! 【Condition】 As shown in the scale image, there is a small stain on one side of the hem, but otherwise, there are no noticeable stains or damage, and it has a nice vintage feel. 【Remarks】 Due to the shape of the collar (with a core) and the balance of the epaulettes, this shirt is more of a mod shirt than a disco shirt. It's recommended to pair it with bootcut or skinny jeans, or cropped pants for a modern look. If you wear something casual underneath, loose pants are also interesting. The material is probably nylon, and you can feel a firm elasticity (it doesn't stretch that much). I also have other JAM items and items that will appeal to those who identify with 60s mods!
