These are ZARA Baby denim pants. The size is 104, so they would fit a child who wears sizes 100-110. They have a Halloween-like design and a cute Mickey Mouse, and I bought them to wear to Disneyland. They have some stretch. There is some damage on the knees, but I've put fabric on the back so the skin won't show. There are some stains, but they are still usable. How about them for Disney Halloween or everyday wear?
