I don't see any reason why it wouldn't be real Brioni. It's a used jacket, after all (regardless of NWOT puffery). I've got two Brioni blazers that I bought used on EBay -- one was @$125; the other @$150. Both in perfect "like new" condition. Thus, I'm not concerned in the slightest by the $300 price. As it is, new with tags (NWT) Brioni blazers regularly sell on EBay for just $600-750 or so; often for a good deal less. I must say though, this auction is an example of how bad pictures can really hurt someone in getting the highest possible price. I mean, the pictures are horrendous. Unprofessional.
