I've been eyeing this Navy Sport Coat by Caruso listed as NWT & around $200. Without being an expert on the subject this seems to be a good deal, but I'm suspicious about the tag in attachment4 & why it is listed so cheaply. Additionally, the cuffs seem to be unfinished - can someone explain what function these unfinished cuffs have? There also seems to be something going on with the shoulders. I'm a true beginner so the more comprehensive answers, the better.
