Emma Stone stopped by the Calvin Klein show at New York Fashion Week clad in an all-red ensemble — Calvin Klein shell top and full skirt with Brian Atwood pumps — that's too fabulous and fiery to overlook. Although this would have been the perfect Valentine's Day outfit, you can just as easily re-create it for your next fancy affair, especially since you can do it for just $30. Just pick up a red sleeveless crew-neck tank and high-waist circle skirt from American Apparel, and pair it with your favorite red pumps — they don't necessarily need to be ankle-strap peep-toes. If a circle skirt is too demure for you, you can also work this look with a pencil skirt (perfect for work) or cropped red trousers, and even red jeans! The options are many, but the key is to keep the look all red or else it'll veer off from its monochromatic path.
