Strange auction. It shows a suit, not sport coat, and no gold buttons, but seller claims it is only a sport coat and does have gold buttons? A lot of money to pay on such confusing information.
I would stay away from this type of listing. The title screams "cashmere", which represents only 1% of the material content. Previously the title said 18K gold buttons, but such a claim is now completely edited out. The suit on the model is different from the item being sold (albeit similarity at the first glance, note the elbow patch on the model). The suit comes with no pants (see Q&A) even though there are measurements for pants!?! Last but not least, listing number of watchers means desperation to sell and thus would be hard to deal with if problem arises.
