A knock-off of Bella Swan's wedding dress (Twilight's heroine, in case you've been living under a rock for three years) just went on sale (at left) and it got us thinking about memorable movie wedding dresses. Forget about people's princesses who wear too much eyeliner or wannabe princesses who get divorced after 72 days: Movies are where the real, unattainable, fantasy love-and-marriage happens. From the classic to the garish, we've rounded up some truly unforgettable wedding gowns from all different eras. Click through to see yards of tulle and lace and dreams and butterflies on gorgeous actresses. Sigh.
