Selling because it's outgrown. The size is labeled 120, but it's suitable for children around 100-110cm. It's a separate type, and preschoolers could take it off and put it on by themselves. Children who are around 100cm and slender might find it a little loose. When my child was 108cm and 18kg, it fit quite well with a little room to spare. We have no pets and no smokers in the house. I hope someone can use it. Thank you! #Swimsuit #School #NurserySchool #Kindergarten #Separate #LightBlue
