This yellow and orange dress by Costello Tagliapietra almost made my heart stop. Even if you're not a fan of bright colors, the cut and details of the dress blew me away. The deep v-neck combined with the short skirt and long train showed off just enought of the model's body to be sexy, but not so much that it was dirty. It was also a bit of an anomaly - it looked comfortable enough to wear to dinner on the beach, but fancy enough to wear to an awards show. I liked a number of dresses on this year's Fall 2011 NY Fashion Week, but this is by far the best dress.
