J. Crew City Fit Cropped Twill Modern Jacket Prototype Sample 40" Bust Size 6

J. Crew City Fit cotton twill jacket is cropped, with 3/4 sleeves, double-breasted, and zip front pockets. I bought this ages ago from a J. Crew tent sale, and you can see from the tag that it is a prototype sample. I don't know if this style was ever put into production, but the tag is stamped Fall 2010. No content tag, but I am sure it is 100% cotton. I love this jacket, it is so modern and minimalist, but was always a bit too boxy on me. The size is 6 but it has a 40" bust and l should think it would fit up to a size 12 or 14. It does have a small fade spot on the front sleeve bicep, see last photo.
