Come rain or shine: Michelle Williams takes her elegant style from winter to spring in one fell swoop

They say you can never be too prepared, and Michelle Williams proved that no matter what the climate, she can dress to impress.

The My Week with Marilyn star showed up to the David Letterman show wearing a stylish faux fur-trimmed black coat buttoned up to keep her warm in the chilly New York weather.

But when she was leaving the studio, the actress revealed she had been hiding an equally stunning dress underneath the cosy jacket.

The Blue Valentine actress, 31, emerged wearing a floral green and white dress that was more suited to sunny spring than the current bitter Big Apple winter.

She appeared to have planned her outfit with precision, as both the neutral coloured coat and the bright dress were perfectly complimented by a pair of simple grey platform heels with sling back straps.

The blonde looked cheerful despite her bare legs in the cold climate, as she posed for the cameras before heading home.
