I received this from my nephew, but I never wore it, so it's in good condition. It says 4toddler, but I think it's equivalent to 100-110 size. 100% cotton. There are names written on the front and back of the washing tag. I will gently erase them before shipping. Please note that there are some fold wrinkles. Please purchase if you understand that this is a used item. I will fold it compactly and ship it. Color...Navy系 (Navy-based) Pattern/Design...Check Material...Cotton Season...Spring, Autumn
