Twilight + wedding dresses = girl-entertainment jackpot?

In what I can only describe as a desperate attempt to attract really young readers with the fashion equivalent of fanfiction, InStyle magazine asked several designers to sketch Bella Swann's wedding dress.

I've always liked looking at the exaggerated lines of fashion designs, so this marketing ploy aimed at the Twilight demographic worked on me. (Okay, and it helped that it was free.) Only one of the dresses looks anything like the dress described in the book*, but the pictures sure are pretty.

*Which I haven't read, but InStyle informs me that Bella's mother tells her that she looks like she'd just "stepped out of an Austen movie", so I'm assuming that means Regency, right?
