Double collar. Please wear it fashionably depending on how you fasten the buttons. The front body is double-stitched with blue check, but it's not heavy and feels the same as a regular shirt. For those looking for a slightly different design. For men, but also for women. 【Size】Men's M size Flat measurement: Length 70 / Width 52 / Shoulder width 41 / Sleeve length 57 / cm 【Material】COTTON 100% 【Color】Red系 Blue系 x Gray 【Condition】No noticeable stains or damage. It doesn't have the crispness of a new item, but it's a beautiful item, I think.
