It's size 9. Skirt only. *Vest sold separately. (The tag with the name on it has been cut off.) I wore this when I was 160cm tall and weighed 46-50kg. I usually wear S-M size. I wore this almost every weekday for about 5 years, so it shows signs of wear. The hook etc. came undone, so I sewed it back on roughly. (Please fix it if you are concerned.) I will ship it in simple packaging. I will be getting rid of it at the end of the year.
