Tilda Swinton in Haider Ackermann | 2011 National Board of Review Awards

Tilda Swinton was in attendance last night for the 2011 National Board of Review Awards gala held at Cipriani 42nd Street in New York City.

The “We Need To Talk About Kevin” star stayed devoted to Haider Ackerman by donning a shiny purple button-front shirt and metallic violet trousers from the Spring/Summer 2012 collection.

I love the vibrant color, the combination is striking. I would have liked to have seen the top pulled out a big more to hang loose like it does on the model. I dig that lazy chic ‘I just threw this on and ran out of the house’ look.

She effortlessly finished off her look with a tousled coif and red lippe.
