Jacket from Japan - very different and cool design. Size 2 Japan size = Small/Very Small. As a Swedish woman, Height165cm, I was able to wear it when weighing around 55-60kg, not having so much musclemass. It was fitting pretty good. Can be a bit tight around the chest - up to C cup I would say works.
So just be mindfull that the jacket is pretty small and tight!

It needs some love as a new button, otherwise whole and clean. Will do a bit of deepclean of more cathair before shipping.
If you feel you need more information - don't hesitate to write a message.

(I don't really have any pictures with it when wearing it and I don't fit in it anymore so can't unfortunately show a picture with a human!)
