This is a children's jumpsuit that was very useful for playing in the snow in winter. The size is unknown, but my children used it for two years each when they were between 1 and 3 years old (around 90-110cm). *I remember forcing my 1-year-old to wear it, even though it was too big, and rolling up the cuffs. It is not waterproof, and the water-repellent function is also gone, so it is recommended for playing in the snow in areas where it snows a little, rather than in areas with heavy snowfall. It will soak through if it gets very wet, so I used to spray it with waterproof spray. It's very cute when they wear it ♡
