Sienna Miller continues to wow us on her “G.I. Joe: The Rise Of Cobra” promotional tour.

The actress looked outstanding when she attended the Japan premiere today wearing a Gucci Fall 2009 ensemble.

The look included an ombré spotted pattern silver and black embroidered spencer jacket and matching pants, plus a midnight blue silk lurex shirt and open toe platform booties from the same Fall 2009 collection.

I would’ve never thought Sienna would wear such a eye-catching look. It’s not very Sienna, but I think that’s was I love about it.

We’re so used to seeing her in florals cute looks or incredibly laid back looks, that this is such a refreshing change.

Apart from the Sydney photocall you will have noticed that Sienna has always worn pants which is something we don’t see very often.

Her hair is longer, her pose is fierce, yet her make-up surprisingly remains light.  I would have expected heavier make-up with this type of look.

What do you think of Sienna’s drastic transformation?
