I bought this this season, pre-washed it, and wore it about twice. I don't like strong smells, so I wash it with additive-free Shabondama Snowl detergent. Please understand that this is stored at home. It has no seams under the arms, so it feels good against the skin and is gentle to wear. The cotton is organic cotton. The "Hadagokochi" (feel of the skin) has been further improved from the 2025 season. 【Material】 Made with a highly elastic rib knit called "rubber knitting," this material allows babies to move freely. "Kijin" (natural) is undyed, offering the "color of the cotton itself." 【Design】 The underarm seams have been eliminated, improving the gentle feel against the baby's skin. The snap buttons alternate colors on the inside to prevent them from being fastened incorrectly. 【Specifications】 Transparency: None Elasticity: Yes Fit: Regular
