This is a very thin knit top from HIROKO BIS. It has black and white stripes, and a black string runs back and forth from the high neck to the hem. The string can be tightened and tied at the hem, allowing you to freely create a gathered design from the collar to the front. When the collar is extended, it's about 15cm, but because it's so thin, it doesn't feel bulky, and it's very comfortable to wear, even though it's a knit. It seems like it would be easy to layer under a jacket. The care label says "dry clean," but I've washed it in a net in a regular washing machine without any problems. It's 77% rayon, giving it a smooth, silky feel. Due to the nature of the material, there are small holes and slight protrusions if you look closely. They are not noticeable when wearing it normally, but please check the last image. Home cleaned only, no ironing.
