EXCLUSIVE AT NET-A-PORTER.COM. When it came time for Danielle Frankel to design her own wedding dress, she took inspiration from her fiancé's shirts and a vintage trench coat to create a piece that was completely unique - the 'Lou' gown was born. Cut to sit effortlessly off-the-shoulder, this cotton-blend poplin style has a waist-defining belt and discreet pockets to store a cell phone so you can take selfies throughout the night. The dramatic hem has a quilted trim to hold its shape and is strategically cut shorter at the front, preventing any missteps when walking down the aisle.
