Blues Clothing has renewed its deal with MGA Entertainment for the girls lifestyle and fashion doll brand Bratz.
With the Bratz licence accounting for £18 million in sales over the past three years, Blues Clothing will continue to produce leisurewear, nightwear and underwear for another four years until 2011.
This makes it the longest contract in Blues' 30-year history.
"Bratz has been a fantastic licence for Blues Clothing," said Suzanne George, licensing director at the firm. "We are very excited to be working with MGA for a further four years and will continue to produce stylish and design led garments for our retailers."
