EXCLUSIVE AT NET-A-PORTER. Joseph Altuzarra created an exclusive '7 Dresses for 7 Days' collection for us last year, and the 'Sunday' version was so popular, we decided to bring it back in a few different colors. This version is cut for figure-hugging fit from stretch-knit fabric woven with marigold stripes. Our stylists recommend unfastening a few of the mother-of-pearl buttons along the front.
