I was mainly interested how Twilight costume designer Wendy Chuck dressed and styled the tall, dark, and fanged Edward Cullen character. In an interview with Wendy Chuck on film.com, Chuck mentions "I [she] wanted to impart in Edward the look of a modern day "Edwardian" gentleman in teen clothes that were suitable to not stand out too much at school. Some of my original choices of fitted pants and long jackets phased into well-fitted designer jeans, off the rack shirts that were tailored to fit in just the right way, a great classic black boot, American Apparel t-shirts and just the right kind of jacket."
She goes on to talk about what interested me the most: that heather grey peacoat. Where did they get it? It turns out that it was made specifcally for the film and makes its appearance quite often throughout the movie. Therefore, it must be one-of-a-kind....do I hear auctioning off? I will be prepared to bid! Other brands they used for costume were Diesel, G-Star, Guess, H&M, Forever 21, Miss Sixty, and Lucky.
Take a look at two clips where you see this coveted grey peacoat (well at least the one I covet...lol.) I must say, overall, Edward Cullen (Robert Pattinson) looks like he stepped out of a Prada look book.
