My FI and dad both want to wear top hats and tails for our wedding. Our wedding is going to be formal so that's fine with me. My mom pointed out men shouldn't wear hats indoors, and our wedding and reception are both inside. So I'm wondering, when would the men have the top hats on? Would it only be during the time we take pictures? Has anyone else done top hats, and if so, how did it turn out?
