I posted this on the Beach Weddings board but appreciate your feedback: I'm having trouble coming up with what to call the attire and how to explain it to my guests. People have started asking us and both of our moms what they should wear to the wedding. I don't want it to be black tie or black tie optional, but I still want people to dress up. The ceremony is on the sand, the reception is in a ballroom. It's a Saturday night with live music as the entertainment (Frank Sinatra cover band). It's a sit down dinner. I am wearing a long dress, we're still figuring out what FI will wear. Bridesmaids will be wearing short chocolate brown dresses, GMs we're still deciding. Any ideas/suggestions?
