I washed an Eastboy cardigan without checking the washing instructions, and it shrunk and became wrinkled. I washed it a week after I bought it. It cost 9,900 yen. The size is 9. Cardigan Lambswool 7G School Knit Quoted from the official website: ■Description A cardigan with an elegant atmosphere thanks to the shimmering silver embroidery on the chest and the texture of the lamb wool. Made with 100% lamb wool, a carefully selected material using only the wool from lambs aged 6-7 months. It has a soft and fluffy feel, a good texture, and is a warm knit. The moderate V-neck opening goes well with inner shirts, and the balance with ribbons and ties is exquisite. The sleeve cuffs have thin, stretchy threads. Also, the seams of the cuffs are neatly sewn with a sewing machine to increase durability. The left chest has the silver goddess embroidery, the proof of 〈Venus〉.
