At the 2010 Toronto Film Festival Rachel Weisz attended two premiere.

The first was “The Whistleblower” where she wore a gorgeous 3.1 Phillip Lim white mixed jacquard jumpsuit which had a cut-out at the back.

A Roger Vivier clutch and beautiful blown out tresses completed the look.

For the Black Swan Premiere she opted for a summery Oscar de la Renta Resort 2011 dress.

Her white silk faille dress with navy silk and white sequin embroidery and a scoop neckline was teamed with Stella McCartney shoes, and Roger Vivier Night Tube clutch.

It’s hard to pick a favourite out of these looks because they are both so fabulous and both so different.

I get a cool relaxed vibe from the Lim jumpsuit and a Park Avenue Princess feel from the Oscar de la Renta dress and they both work for me.

Can you pick a favourite?
