The Twilight Promotional tour made it’s way to the UK today with the film’s most famous trio; Robert Pattinson, Kristen Stewart and Taylor Lautner appearing at the London premiere of Breaking Dawn Part 1 at Westfield Stratford. Kristen pulled out her second show-stopping look in as many days; this time a black embellished gown from the new spring collection by Roberto Cavalli. Cavalli is a not normally on the list of preferred designers that Kristen tends to wear but she picked the perfect design to suit her look. Whilst the gown is very pretty it also has a slightly gothic edge, perfect for a vampy film and Kristen image. She teamed the dress with Jimmy Choo pumps and an Alexander McQueen black leather belt.
