The coat first came to attention when the picture's costume designer, Wendy Chuck, claimed she made a last minute dash to U.S. clothing chain Nordstrom and picked out the BB Dakota item to be worn by Stewart's character Bella Swan in 2008's Twilight.
Executives at BB Dakota subsequently began marketing the blue cotton coat emphasising the item's link to the vampire franchise, using the line, "Bella Swann (sic) wears this jacket in Twilight and scores the hottest vampire in high school, and so can you!"
But the advertising ploy has riled bosses at Summit Entertainment, the studio behind the Twilight films, and they filed a lawsuit against the clothing company on Friday (11Jun10) claiming copyright and trademark infringement.
The lawsuit seeks an injunction against further sale of the item and demands BB Dakota bosses turn over all profits earned from the sales.
Film bosses also want the clothing firm to "deliver to Summit for destruction all Bella Jackets," according to The Hollywood Reporter.
