This Halston jumpsuit (from F/W 2008) and I would have had a fabulous time at the Costume Institute Met gala this year. It fits the theme of the American woman, it being Halston and all. I would have also worn these giant dark brows from the Prada runway (also F/W 08). Shoes or clutch wouldn't have necessarily mattered, I'd probably do something nude or chocolate brown. And they would probably be vintage.
