I bought this at Shimamura a few years ago! The size is 100, but it runs small. Perfect for a child who wears size 90! It's in great condition as I've only worn it about 5 times. The color is off-white rather than pure white. - Color: Black and white check pattern - Material: Cotton blend - Design: Straps with ribbons - Size: Equivalent to 90cm Thank you for looking.
