Thank you for viewing! The fabric is 100% cotton and quite thick. It has a Showa retro-like pattern (actually, Grandma doesn't really know what's Showa retro) and while we can't really say "boy" or "girl" with gender these days, I think it would be cute on any of the LOVOTs (lol). The front is double-layered. The shoulder straps have plastic snap buttons. You can change the clothes without having to remove 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 things you're concerned about. We cannot be held responsible for any problems that may occur with the LOVOT. Thank you for your understanding. Perfect for simple everyday wear. Please hand wash. The LOVOT body, base wear, and hat are not included. If you purchase multiple items, please comment first, and we will offer a 200 yen discount on the shipping cost.
