I was looking at some Brioni sport shirts on EBay. The ones I like are tagged Brioni SPort, and from the Cruise collection. I have 2 questions: 1. Is this a lower step in quality, or just it just reflect a sportier look? 2. I read somewhere on Ebay that you should buy a size higher in Brioni, hence if you wear a medium sized sport shirt normally you would require a L. Anyone have any experience in this area?
