The stars kicked off this year's New York Fashion Week in style at the amfAR New York Gala. Waving the Aussie flag was local gal Rose Byrne, looking illegally beautiful. Her pale pink, Ralph Lauren Collection gown had an effortless elegance about it, which she accessorized with a bling-tastic diamond necklace. Flame haired Karen Elson brought out her inner bombshell a white fringed frock from Versace, which looks to be a variation on the dresses worn by January Jones and Blake Lively. Snap! Helena Christensen rounds out this stylish trio, who went for a more casual approach in a blazer, visible bra and shorts combo. Who do you think worked it best for this pre-Fashion Week bash? Romantic Rose? Sexy Karen? Or casually chic Helena?
