Trash the Dress?
A popular new trend in wedding photography is called "trash the dress." As this photographer explains, "Despite what the name implies, a trash-the-dress photography session doesn’t necessarily mean destroying the dress; it simply means doing things in your wedding gown that you wouldn't do on your wedding day ... Get it dirty. Get it wet. Roll around in the mud. Drench it in the ocean. Totally trash it, and get some great fun pictures while you do it!"
Sounds good to me! Especially if you got a good deal on your gown :)
