Product name: Basic Clay bodysuit (blank) When you order from us, you know it's in the right place. Not just the product, but everything around it. The rompers contain no toxins and are produced in a sustainable way in an ethically responsible factory. We do the printing ourselves, in a sustainable way, from our own store in Amsterdam. So completely locally produced! All our textiles are certified with STANDARD 100 by OEKO-TEX®. This is one of the world's best-known labels for textiles that have been tested for harmful substances, which stands for high product safety and product confidence. So safe for a baby! In terms of sizes, we have made it easy, because you can use the number of months that we indicate for the rompers. Of course, it is possible that a baby is just too small, too big or too plump (chubby = cute). In that case, you can use the following measurements: 0-3 months: 62 3-6 months: 68 6-9 months: 74 9-12 months: 80 12-18 months: 86
