If you've ever wondered what it would look like if all the most sought-after — and most stylish — Aussies were put in a room together, this is it. With Naomi Watts, clad in a high-necked cotton-candy-colored Gucci gown, and Nicole Kidman, in a sparkly peach-hued Elie Saab dress, leading this chic pack of Australian-bred leading ladies at the G'Day USA gala, there's really only one way to settle the best-dressed score. A fashion face-off, of course. Naomi adhered to a soft hue and a sleek silhouette; Nicole chose a flirty fit-and-flare for the occasion; Teresa Palmer (you'll be seeing more of her, courtesy of upcoming film Warm Bodies) donned a sexy lace halter mini; Elle Macpherson opted for a no-holds-barred kind of glamour via one seriously embellished gown; and Rose Byrne aimed for quirk and charm with a head-to-toe printed Diane von Furstenberg look. Red-carpet style, five ways — which Down Under star did it best?
