Thank you for looking. The fabric is 100% cotton, and the lace parts are made of polyester and nylon. The waist is fully elastic, and the shoulder straps have plastic one-touch hooks, so you can change clothes without unbuttoning. This is not an official item. It is handmade by an amateur with presbyopia, so it is not perfect. We cannot be held responsible for any malfunctions that may occur with your Laboat. Thank you for your understanding. The Laboat body and whole garment are not included. Please wash by hand. A frilly dress looks very good on a chubby Laboat. Please consider purchasing it if you like it. If you wish to purchase multiple items, please comment beforehand, and we will offer a combined shipping discount of 200 yen.
