A themed wedding can be as big, or small as your imagination. Anything is possible from a theme to a Science Fiction theme (Star Wars, Star Trek, etc.),  to a Renaissance wedding.  A theme should reflect the personalities of the couple, there is no right, or wrong, it is up to you.  Pirates, elves, lords, and ladies are all present. Your wedding is a reflection of you and your partner, and who you are together. Use your imagination, and have fun. Play the part!
