I have accumulated enough AmEx points to cash in on a $1200 gift card to either Saks Fifth or Neiman Marcus. I am going to NYC in a couple weeks and am looking to pick up either a navy blazer or a new suit. How do the suiting selections differ at these two stores? I am specifically looking for Boglioli, Caruso, Isaia and Jil Sander. Do both stores carry these lines?
