I only rinsed it in water, but the color didn't suit my child, so they haven't worn it. As shown in photos 4 and 5, there are some loose threads from the beginning, so please be aware of that. I think it won't be a problem for wearing, but please purchase at your own discretion. A romper made of soft and airy cotton muslin. It has a round neckline with a button at the neck. Long sleeves. It has snap buttons at the crotch for easy changing. The cuffs and leg openings have soft, thin elastic.
