This is a size 100, but it runs a bit small, so it's recommended for children around size 90. My daughters wore these as matching outfits. I'm selling these because my younger daughter has become picky about what she wears. The color didn't photograph well due to the lighting. The color is as shown in the last photo. It's a beautiful purple with a very cute design. These are not new, so please refrain from purchasing if you are sensitive to used items.
