It is size 1 which makes it fit a waist from 72-80 cm.
However in my experience it fits more like a 75-80 cm waist and therefore was always a tiny bit too big on me. 
It's in a overall good condition, just not perfectly ironed and I will try to remove all of the white lint when I ship it out. Also the ribbon in the back is sightly fraying (I took a picture) If you have any questions whatsoever feel free to send me a message <3
