This minxy little number wouldn't wash 'below stairs', would it Joanne Froggatt?
The 33-year-old British actress, best known for her role as dowdy Anna Bates, the head housemaid in Downton Abbey, looked A-list incredible for the London premiere of her new film Filth in London on Monday.
With the huge success of Downton Stateside, Joanne has spent many weeks in Hollywood hob-nobbing with the great and the good of the movie business, not to mention attending glitzy parties. It's definitely having an impact on her style too - she has LA high-maintenance grooming written all over her, but with a nice British edge. Just the way we like it.
We expect big things from this one.
