This is a long-sleeved, thin knit sweater from Yamadaya Aga. The neckline is asymmetrical and cute. There is no size label, but I think it's about a size S-M, but it's made of stretchy fabric, so I think it will be easy for anyone to wear. I have never worn it. I remember it cost about 10,000 yen at the regular price. Thank you for looking.
