When wearing a yukata or kimono, you use towels or other items for padding... By wrapping it over undergarments, you can make your waist more cylindrical, making it easier to tie the obi. This is made by folding two commercially available towels (32-35 cm wide, 75-80 cm long) in half and attaching a string (80-90 cm long). You wrap it around your waist, cross it in the back, and tie it in the front. I received a message from a customer who purchased one saying they preferred strings over Velcro. I think strings are easier for anyone to use. When wearing a yukata, etc... it's made with towels and tenugui (hand towels) and double gauze, so it absorbs sweat. I try to sew carefully, but it is handmade by an amateur, so please understand any imperfections before purchasing. I may use recycled wrapping paper for shipping, so please be aware of this. ★I am also listing this on other sites, so please understand that I will prioritize the first person to purchase.
