We already know that Kristen Stewart's wardrobe in Twilight and The Twilight Saga: New Moon has led to increased revenue for companies such as Billabong USA (see here).
Now, there are a couple of other sources for the Bella jacket look, in case you are interested.
One such is from Fred Flare, who has a jacket quite similar to that which Kristen Stewart wore in Twilight on pre-order for $64.00 (pictured in slideshow below).
Another is ModCloth, whose pre-order jacket boasts the same pricetag (pictured right), but whose jacket includes a hoodie (whilst Fred Flare's does not).
Small difference from the BB Dakota jacket that Billabong has up for sale.
