Attention!!! The size is listed as 60cm, but it's actually 0-3 months (50cm). *I selected 60cm because there was no option for the correct size. My newborn was bigger than I expected, and they outgrew it without ever wearing it. It's a shame because I really wanted them to wear it. It has been pre-washed. There's a snap button on the side of the neck. A one-piece design with a soft and comfortable cotton top and bodysuit. Round neckline with ruffle details. Short puff sleeves with ruffle details. Yoke design. Snap buttons at the crotch make it easy to change clothes and diapers. All-over print. Layered bodysuit that looks like a top, preventing the belly from showing.
