I have kept this at home, unworn, after only rinsing it in water. Please purchase only if you understand this. 100% cotton Gray Newborn The following is a product description: This is a 2-way all-in-one garment featuring mascot-like animals. The main design is a border pattern that prevents the outfit from looking plain, and it highlights the cute accents. The gentle touch of organic cotton is also appealing. A separate fabric is set on the sleeves to prevent scratching. The buttons on the crotch area have different colors to reduce the chance of buttoning them incorrectly. There is no "backing cloth" on the back of the motif.
