I was originally thiking a linen tan/khaki suit, but he thinks he will be too hot. So the obvious second choice is khakis and a white shirt. What seems to be the normal thing to do? I havent narrowed down my dress yet, but from what I have narrowed it down to none of them are what I would consider casual nor are they over the top and something I would wear if I would get married at home in a church. Thanks for your input!
