Used once and then stored at home. Purchased from a select shop for around 5,000 yen. Length: Approximately 85cm Width: Approximately 34cm (measured at the top button) It's slim, but it stretches somewhat due to the gathers under the armpits and in the back. Please feel free to comment if you have any questions. I'm looking forward to hearing from you! *:.。..。.:*・'(*゜▽゜*)'・*:.。. .。.:*
