Michelle Mason one shouldered mini dress with leather trim

Extremely hard to find Michelle Mason mini dress, and authenticated (RN number on tags as well as designers label). No flaws or imperfections, NWOT. Leather trim on top of sleeve, extremely flattering and comfortable LBD. Very hesitant to have this leave my closet, only willing to do so for the right price; price is firm. I will give consideration to reduction only for large bundles. <3
