Thin knit. It's a little sheer. It's stretchy, so the size is listed as F (Free Size). It's a high neck and cute, and since it's white, I think you can wear it with any bottoms. The length is long, and there are slits on both sides of the hem. Purchased about 2 years ago. Only tried it on, and have never worn it for a long time. I'm selling it because it didn't suit me. Retail price: 6600 yen Color: White Material: Acrylic/Rayon (synthetic fiber) Neck: High neck/Turtleneck Season: Spring/Summer/Autumn
