If Martin Scorcese's classic film about a vigilante New York taxi driver doesn't sound like a film full of fashion inspiration, then you haven't seen Jodie Foster's outfits. The movie may be controversial, but the style of its heroine, Iris, is undeniable. With fashion’s bout of '70s nostalgia still going strong, her look remains as covetable now as ever before. Think miniscule shorts, wide flares, sunglasses as bright and bold as you dare, and large-brimmed sun hats. We have her pegged as our summer style muse.
