This is a lace-knitted sweater by Miss ALICE. There is no size listed, but I believe it is equivalent to a size L. The width is approximately 50cm, though this is a rough measurement. You can change the look by wearing a colorful inner layer. The sleeves are long, designed for "moe sleeves," and the design and knitting are quite elaborate and rare. I have worn it a few times, but I don't have the opportunity to wear it anymore, so I am selling it. I have priced it quite low, so I am not considering lowering the price for the time being.
