This is a CHAPS shirt. Shoulder width: 49 cm Length: 78 cm Width: 59 cm Sleeve length: 54 cm Since there was no size indicated, I've tentatively listed it as L. I bought it used for around 7000 yen. The purple stripes and the fit go well with a Sullivan setup. I think it's also good as an accent color for a black outfit. Since it's CHAPS, the quality is solid. CHAPS is often associated with casual items, but I think this kind of formal shirt is rare. I'm 174 cm tall and weigh 56 kg, and it's a bit oversized on me.
