Jut got a dark olive 100% virgin wool Giorgio Armani blazer off Ebay and wondering if I can wear it with regular Levi's or do I need Armani or other designer jean? Can people In the "know" tell? Also, is there anyway to verify if it is an authentic Armani blazer? It has a tag on the right inside pocket above that says Giorgio Armani made in Italy, black letters white label. On the left side it has a Saks Fifth Avenue above pocket on black tag white cursive. Below pocket has dryclean only tag. The collar has a Made in Italy tag. Any info would be most appreciated Thank You.
