The fashion line - called Lily Loves at New Look - features dresses, jewellery and footwear, ranging from£5 for a flower ring to£50 for the Fox Trot Ruffle dress. Highlights from the collection include a maxi Graffiti sundress, embroidered with lyrics from Allen's songs, a Gandalf print shift dress, available in gold and candy, and a black floral Gosford baby-doll dress. The range will go on sale in 312 New Look stores across the UK and Europe.
New Look head of fashion communications Sarah Walter said: 'If there is anyone that defines the art of modern dress-wearing, it is Lily Allen. New Look is delighted with the collaboration.'
Allen said: 'I've been wearing things from my range for months. I just feel comfortable in dresses; they cover up all the bits I don't like and they're easy, plus they're appropriate for almost every occasion.'
Pop star Allen has become the latest celebrity to collaborate with retailer New Look. She follows in the footsteps of Hollywood actress Drew Barrymore, who last month was revealed as the face of designer Giles Deacon's new Gold collection for New Look.
TV presenter Kelly Brook is also in her third season of designing for the retailer. Brook designed a spring/summer swimwear range last year, an autumn/winter lingerie collection this year and another swimwear range for this spring.
