I purchased this item from a craft store. It's handmade by the craft store. I only used it indoors for taking photos. There are no stains, but please purchase only if you understand that it is handmade. How about it for a child who loves Pikmin? I think it can also be used for Halloween ♪ The color is close to navy! The inside is blue. I don't know the exact size, but it was a bit big for a child under 1 year old, but they could wear it. A 4-year-old could also wear it, but it was a little tight. I think it depends on the individual, but it seems like it would fit a 2 or 3-year-old perfectly. * No pets, no smokers.
