Flaunting head-to-toe Lanvin for the design house's, 'Lanvin Loves Fashion night in the Big Apple this week, supermodel and active philanthropist, Iman looked positively stunning. This undeniably luxurious cocktail dress with synched waist and off the shoulder, slash neck displays that enviable chassis that has earned Iman her supermodel millions and sculpts a silhouette to die for. Satin seems to be hot on the heels of leather and lace of late, creeping up the style stakes of this season's hottest fabrics. We saw it on the beautiful Angelina Jolie yesterday, Iman today and we're sure many famous faces of tomorrow. Mark our words - you saw it here first! A sultry flash of flesh and skimpy hemline bring a touch of sex appeal to the whole ensemble while a more demure, three quarter-length sleeve ensures the outfit remains proper. Even supermodels love to stay cosy in the cooler months so a longer sleeve is the prefect way to stay stylish and snuggly in one swift movement. If you're looking for a glamorous addition to your LBD evening wear collection then a short, satin vestment is your way forward so browse our pick of today's best for some slinky inspiration.
