This is a romper from the American children's clothing brand, kate quinn. I imported it personally from their official online shop. The size is 6-12 months in American sizing. It's roughly equivalent to 70cm in Japanese size. The material is 95% bamboo. It stretches very well and is a thin, smooth fabric. I've inspected it myself, and there are no stains or other marks. There are a few pills on the knees. Please check the 4th image. The unique vegetable pattern is not found elsewhere and is very cute ✨ It's a pattern that can be worn by both girls and boys! Babies often spend time at home in their underwear, but I loved this romper because it looks stylish in photos(^^) Please consider it! - Brand: kate quinn - Size: 6-12 months - Design: Vegetable pattern - Material: 95% bamboo, 5% Lycra
