Danielle Frankel's 'Sasha' gown is brimming with romantic elements, like a draped cowl neckline and decorative covered buttons diagonally tracing the hip. Cut from glossy silk-charmeuse, it has a slightly loose fit and falls to a pooling hem with a knee-grazing split. The languid bustle has a loop at the end, so you can work the room with ease on your big day.
