Just Jeans denim jacket

Blue button up denim jacket from Just Jeans. 

In great, lightly preloved condition. No major signs of wear except for two small marks - one on the front (see photo), and one on a sleeve that is half the size of the stain in the photo. These marks are barely visible.

There are blue buttons around the inside of the collar so I think this may have had a detachable collar at some point (but doesn't now).

Size women's medium.

100% cotton.

Grade (what does this mean?): A/B

Measurements:

Chest (armpit to armpit, across the back): 54cm

Length: 61cm
