This is a padded kimono. It has basting threads still attached. The blue threads are also likely basting threads. I believe they are there to keep the cotton padding from shifting. There are some areas that need repair (see photos 14, 15, 16, and 17). I believe the material is cotton. Length: Approximately 133.5cm Sleeve length: Approximately 50.5cm Sleeve span: Approximately 63cm Front width: Approximately 27cm Back width: Approximately 30.5cm Thank you for reading. I have started listing items because recycled kimonos have begun to come to me. (They were destined to be discarded if I didn't take them.) I am not an expert on kimonos. I am especially unable to determine the material. Please understand. I would like to enjoy Mercari with kimono enthusiasts. #Tanzen
