Picking the perfect wedding dress is a big deal for every bride. But when it’s a dress that millions of girls all over have been picturing in their heads for the better part of a decade, selecting the wrong gown could mean catastrophe.

And maybe that’s why rumor has it the crew working on Twilight: Breaking Dawn chose Zac Posen to design character Bella Swan’s Victorian-inspired wedding dress.

The book describes the dress as something that “stepped out of a Jane Austen movie,” meaning very Victorian; lots of lace, mounds of tulle and slightly overworked. Posen is pretty well known for his frequent hat tipping to old-school glamour while still making modern clothes, and anyone who’s seen photos of his work can attest to its visual appeal.

And really, that’s the most important thing about this dress — it has to live up to the dreams and fantasies of millions of Twilight fans across the globe. Kristen Stewart, the actress who plays Bella, said she had some input in picking the dress, but that it was “pretty much up to Stephanie Meyer (the author)” to find the prefect frock. And I'm not at all surprised that Posen got tapped to fulfill the writer’s wishes. Look below at a couple of my favorite Posen dresses!

ET Online broke the news about Posen, mentioning that he designed both the suit and the halter-top gown Ellen DeGeneres and Portia de Rossi wore at their wedding. He also designed the lacy fishtail gown supermodel Coco Rocha wore on her special day.
