Suzuro Belt LL. A popular, classic Datejime (under-kimono belt). It's a good product that doesn't constrict or loosen. I had heard it stretches, but I didn't expect it to be this much. The size was too big for me, so I'm selling it. It's breathable and lightweight, so it can be used all year round. I've used it twice and it's still in good condition. Size: LL
