So we are attending a wedding in the middle of August. We are expecting it to be relatively warm. The venue is a state park, I believe ceremony is outdoor and reception indoor. The bridesmaids are wearing bridesmaids dresses from David's Bridal, and the bride is wearing a blue gown (her second wedding so she didn't want to wear white). The groom and groomsmen, from what I understand, are wearing jeans and some button up shirt I want to say white. I was going to wear a sun dress either way. But is it appropriate for my husband to wear cargo shorts to this? I know a couple of you gals had weddings in the park. What do you think? Can he wear tennis shoes?
