Length: Approximately 67cm Shoulder width: Approximately 45cm Width: Approximately 50cm Measured flat. Please note that there may be slight variations due to amateur measurements. It's labeled as size S, but it's equivalent to M. It fits perfectly for someone 172cm tall and weighing 63kg. I've only tried it on twice, once at the shop and once at home. As shown in photo 8, there's a slight stain on the price tag, please be aware of this. Please understand that this is a used item and has been stored at home. Thank you.
