Michelle Williams was in Paris on Wednesday night for the premiere of her latest movie, ‘My Week With Marilyn.’

The romance of the city must have been contagious, as Michelle wore a princess-esque Christian Dior Spring 2011 Couture gown rather than a prim, neutral-coloured frock that she tends to favour.

Her pale pink strapless silk gown poufs out into a large bell-shaped skirt with a rise-and-fall hemline which leads out into a train.

On a bed of tulle, I love how the silver, lightly embellished floral design cascades from the top of the bow accented bodice down one side of her gown.

My best guess for this drastic style change is that Michelle gave her stylist the night off, and let her six-year-old daughter choose her look for the night, as it’s the stuff little girls dreams are made of.

Silver Dior peep-toes and a glossy red lip colour which matched nails completed this BDOTW worthy look.

Are you relieved that Michelle has stepped out of her comfort zone?
