Rachel McAdams in Elie Saab green gown @ TIFF 'To The Wonder' premiere

Rachel's fashion is always one to watch, and she somehow manages to do exactly the opposite of what everyone would expect! This was a lovely choice - dark forest green, high neck with self-tie, subtle pleats at the top, with a skirt that is all curvy and va va voom. And if I'm not mistaken, the tie at the back drapes all the way down her back! It has a neat floor-sweeping cape effect .. and since we haven't seen a one-sleeved dress on the red carpet for a while, Rachel's first appearance at 2012 TIFF has become instantly memorable.

As for the styling, her eyes are quite sharply lined, her hair is pulled back into an updo, and she kept jewellery to a minimum. This look is all about the luxurious fabric - check out the close-up below, it's sumptuous and rich.. and perfect for the upcoming fall season. No online shopping here, but there is a blue one-sleeved dress from the Fall/Winter 2012 runway online over at Boutique 1.
