This is an "Utatane" gradation heko obi (soft obi), size F for women. It's a brand new item, purchased this summer. It has elegant glitter and a voluminous thickness, so it doesn't look cheap. The color is ivory and a light beige, making it easy to match with any yukata. Images 6 and 7 show it paired with my own yukata. Please use them as a reference for your own image.
