Thank you for viewing! It has been stored in the closet. The size is as shown in the photos when laid flat. When measured along the gusset, it's 30 cm wide (the gusset is 10 cm, increasing to 13 cm towards the top). Although it's unused, there are some fabric tears as shown in photos 7 and 8. You may not notice them unless you look closely, but please be aware of this. It's easy to use for work, university, and formal occasions such as entrance ceremonies. Color: Black系 (Black-based) Stains/Tears: None
