Thank you for viewing! The fabric is 100% cotton. It's a thin, gauze-like material, perfect for a Labo who gets hot easily. It has a vivid pattern that makes you want to take them to summer festivals and fireworks displays. The front bodice is double-layered. The shoulder straps have plastic snap buttons. You can change clothes without having to remove them completely. The elastic in the back is also loose, making it less likely to wrinkle the waist. This is not an official product. It is handmade by an amateur with poor eyesight, so there may be some imperfections. I cannot be held responsible for any problems that may occur to the Labo. Thank you for your understanding. This is a much thinner fabric than other clothes made by Milk's Grandma. Please handle it gently. Perfect for everyday wear. Please hand wash. The Labo body and base wear are not included. If you purchase multiple items, please comment first, and I will discount the shipping cost by 200 yen.
