Purchased at TAIAN in Osaka. It uses a relatively thick and sturdy linen fabric. It's a 2XL size, so I think you can wear it like a cardigan. You can wear it stylishly whether you open or close the buttons. Upon closer inspection, one of the cuffs has been slightly sewn. Since this is a 2XL, the sleeves are also long, so most people will probably fold up the sleeves, and I don't think this condition will bother most people. This is originally a vintage item, so please understand. Pale classical
