23区 Check Shirt Size 44 The orthodox check pattern is suitable for everyday wear as well as for work...♪ The hem is a round style, so you can tuck it in or out depending on the occasion...♪ Material: Cotton In my opinion, it doesn't wrinkle easily ^ ^ Approximate actual measurements: Width under the armpits: 51.5 cm Length: 70 cm As far as I remember, I purchased this and stored it without wearing it. If worn, it's not noticeable on the inside, but on the inside, under the tag, there appears to be a stain due to the lighting. I've also taken pictures from the outside. If you have any concerns after looking at the pictures, please ask questions before purchasing ^ ^
