Thank you for viewing! The fabric is 100% cotton broadcloth. The bunny applique is attached with an iron. I don't think it will come off, but if it does, please reattach it with an iron. 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, so wrinkles around the waist are less likely to appear. This is not an official product. It is handmade by an amateur with presbyopia, so there may be some areas of concern. I cannot be held responsible for any problems that may occur with the LOVOT. Thank you for your understanding. Please use it for simple everyday wear. Please hand wash. The LOVOT body and base wear are not included. If you would like to purchase multiple items, please comment first, and I will discount the shipping cost by 200 yen.
