Purchased from a select shop. This knitwear is from Yamagata, famous for its knitwear. The material is excellent and feels very soft against the skin. It's made with a blend of high-quality extra-long staple cotton and silk. The shape seems to be carefully designed, as described in the third image. There's a small slit in the sleeves. It's a bit pricey, but I have it in a different color, and it's thin and very comfortable. I no longer need it due to a department transfer, so I hope someone will wear it! I think it would be great for business casual wear. Material: 80% cotton, 20% silk, hand washable Size: 38, Length 52cm, Width 40cm, Sleeve length 40cm (measured from the neckline due to raglan sleeves), three-quarter sleeves Color: Yellow I like and often shop at Baycrews, Spick & Span, Framework, Journal Standard, IENA, United Arrows, Ships, Beams, Abahouse, etc!
