Matching children's clothing in size 100 is available. Made with knit fabric. It's a turtleneck shirt with sleeves. Handmade using a home sewing machine. Please consider this if you don't mind. Please check the size in the photos. It's a DSS size. Suitable for a 3.1 kg dachshund, a little large, or a 3.4 kg dachshund, which is a perfect fit. You can wear this shirt alone indoors, and layer a vest over it for walks. It was made as a set with the reversible vest in size S that I'm also selling. If the size fits, please consider it. Thank you for looking.
