Size: 6 years old My child wore this when they were 3-4 years old, so I think it's around size 90-100. There are spots on the stomach area, like discoloration or faded spots. There's some staining on the cuffs. We also received this as a hand-me-down, and the tag was already cut off at that time. The fabric is durable, so it can be worn without worry. There is a general feeling of use. Please understand that this is a used children's clothing item.
