I was recently invited to a wedding this summer on July 4th weekend in DC. The attire is black tie for the first day and business casual for the second. I was wondering if between midnight blue and black, which one I should be looking to roll with. Im interested in the dark navy, but I'm not sure if it would be appropriate for the occasion. Also if anyone has any color/material ideas for the business casual that would be great too. Thanks again SF!
