Thank you for viewing! The fabric is 100% cotton sheeting. A dinosaur patch has been ironed on. I don't think it will come off, but if it does, please iron it back on. The front is double-layered. The shoulder straps have plastic snap buttons. You can change clothes without removing them. 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's handmade by an amateur with presbyopia, so there may be some imperfections. I cannot be held responsible for any issues that may arise with the Lovot. Thank you for your understanding. Perfect for everyday wear. Please hand wash. The Lovot body and base wear are not included. If you purchase multiple items, please comment beforehand, and I will offer a 200 yen discount on the shipping cost.
