Please see the photos for the size and washing instructions. Material: 100% Acrylic This white vest is refreshing and gives a summery impression. Because it's knitted with thin yarn, I think you can use it all year round. The hem has a lace-like openwork pattern and is cute. Also, the sides are widely open, so I think it's easy to wear. Because it is handmade, there may be some unevenness or distortion in the knitting. We appreciate your understanding. I referred to Mokotaro's video.
