This is a stretch shirt from wjk / Doublet. It is a used item, but it has only been worn 2-3 times, so it is in relatively clean condition. It's a clean-looking shirt, but it also has a casual feel, so I think you can wear it both on and off. It's designed to be worn tight with stretch. Size M Shoulder width 43cm Body width 48cm Length 69cm Sleeve length 64.5cm. Please allow for some errors. Material: Cotton 54% Linen 45% Polyurethane 1% Color: Navy Made in Japan Thank you for your consideration.
