There was very little not to love about iconic beauty Iman's look last night. The model was glowing on the red carpet of the New York City Ballet's Fall Gala with smoky eye makeup and tousled curls. Her style was capped off with a sparkly hair accessory, adding just the right amount of brightness to her elegant black gown; the juxtaposition of her dark eye palette and dressed-up barrette worked beautifully. Like Iman proved here, the right hair accessory can add instant glamour to your entire ensemble.
