Embarrassed. This is a wedding, not a SciFi convention or a Renaissance Faire. I appreciate that all wedding attire is at some level a costume and a symbol, but it is always worrisome when people want an excessive theme for their wedding.
The theme for your wedding is that you are committing to bind yourself legally, spiritually, financially and physically to another person for the rest of your life. Take it seriously.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
