No one does a cocktail dress quite like Dior. I've always loved a bright shot of yellow for evening (think Michelle Williams in that iconic yellow Vera Wang gown with a slick of red lipstick for the Oscars a few years back), and this dress had that plus a sheer lingerie vibe, which is another thing I love for evening. It's basically perfection packaged in lace and silk chiffon. Another upside to adding some color to your nighttime ensemble: you'll definitely stand out in a sea of boring little black dresses.
