The tag says 4Y, but it was worn by a 3-year-old. I think it's about 95cm. It was only worn for one season, and in combination with other swimsuits, so it's still in good condition. A colorful abstract patterned 4Y size one-piece swimsuit with a cute design featuring ruffles and a ribbon. - Design: Colorful abstract pattern - Material: 82% Polyester, 18% Elastane - Size: 4Y - Features: Ruffles, ribbon on the sides Thank you for looking.
