Thank you for viewing! Beige long-sleeved knit from ZARA Elegant design with pearl buttons The white collar and cuffs are not removable. The material is written on a long black tag, but I don't have the language skills to confidently announce it, so I can only tell you that it's written in Japanese as rayon, nylon, and polyurethane. Please refrain from purchasing if you are concerned, as some materials may not be suitable for your skin. Home washing is possible. I think it's a fabric that doesn't wrinkle easily. Size (actual size) Underarm 41 cm Total length 55.5 cm Sleeve length 53 cm It feels more like a smooth touch than a knit. There is a small white dot under the collar on the front. It's not a stain, but it seems like the thread is woven in. You probably won't notice it when you wear it. There was a similar white dot on the hem of the front. There is also a light brown dot on the hem of the back. I completely forgot about this item, and I'm not sure when I bought it. I think I bought it without noticing it at the time of purchase. It doesn't seem to be a stain that appeared later. Even though it's unused, it's been stored by an amateur for a long time, so I'm looking forward to purchases from those who understand that.
