Grammys 2008

The 21-year-old British singer, best known for her song "Smile," quickly got the attention of the fashion world with her pairing of formal dresses and tennis shoes after breaking onto the music scene in 2006. In May, Allen used her fashion influence to launch her own clothing line Lily Loves, for New Look stores in Britain. The line, which coincided with the launch of Kate Moss's line at Topshop, includes bright dresses, shoes and accessories inspired by Allen's own original style and healthy physique. "You know how I feel about fashion: It's for everyone, not just a load of super-skinny models," Allen says. While her line will continue to be sold only in the UK, Allen will most likely be in the states for the Grammys. She is nominated for the first time this year for her album Alright, Still.
