First off ,where ever you are going to hold your wedding ceremony make sure it has good heating or don't rent it! During the wedding there will be 3 changes of clothing.One to meet and greet, heavy and hot, I'm talking about the clothes here!. Second is the actual ceremony,a nice white dress is good as the ceremony does not last that long and many many pictures will be taken, Third when you do the tour of the tables, your discretion. If it was anything like my wedding by the time you get to do the rounds of the assembled guests you won't care as you will have your beautiful bride next to you and ....well you can imagine!
