Initial Ideas For My Trailer

I have thought about what I want to do for my own trailer, my initial thoughts were that the film will be based on three bridesmaids that really do not get on, on the day of their friends wedding things really don't go to plan when everything that is meant to be perfect goes wrong! a day that is meant to be full of fun, laughs and happiness goes to a complete disaster. This is my initial thoughts so some things will be changed, I will do a mock run through of what I think will work and find out if this is successful or not. I want the trailer to be funny, girly and very entertaining.
