I purchased this about three years ago from Gilt. It's tight-fitting, but it seems easy to wear because it has elastic. Since it's from overseas, the sizing is a bit unclear, but my daughter, who is currently 132 cm tall and weighs about 26 kg, wore it from the second to fourth grade of elementary school. For reference. She probably wore it about 10 times. It's about time for her to outgrow it, so I'm listing it. The snap button on the left hip is missing, so you might want to have a similar button attached. Since there's a missing button, I marked it as slightly dirty, but I don't think there are any stains.
