Chūran Modified School Uniform

This is a Churan (a type of Japanese school uniform jacket). I purchased it used, but it doesn't fit me, so I'm selling it.
I tried it on once.
Although I bought it used, it was described as new, so the condition is very good!

- Color: Navy

Length: Approx. 83cm
Sleeve Length: Approx. 61cm

Thank you for looking.
