I am almost 100% sure this jacket is NOT Dior Homme by Hedi Slimane, the zipper pulls and details don´t correspond with any of the collections produced so far, but maybe it´s Costume National? I remember they´ve had some really nice leathers with similar detailing as the one shown here and they were MUCH more affordable than Dior´s, which tend to be very overpriced. Rick Owens and Ann Demeulemeester are also a safe choice for really high quality leathers with a certain, distinct style, as far as I remember, often under the high Dior pricetag.
