The Les Misérables star proved white is where it's at this summer as she sizzled in a chic two-piece at the VIP Las Vegas screening of her new film Lovelace last night (4 August).
Two-pieces have been all over our fashion radar for a while now, so we can't get enough of Amanda's minimalistic Stella McCartney outfit.
She kept things subtle in the shoe department with taupe courts by Calvin Klein, accessorising with a dainty silver ring and luxe blow-dry.
And it's not just her wardrobe we're lusting after - the pretty blonde upped the ante in the beauty department too, adding a dash of drama with vampy red lippy.
Loving your work, Amanda!
