EXCLUSIVE AT NET-A-PORTER. Cecilie Bahnsen's mattelassé silk-blend dress is a perfect example of how the designer romanticizes simple silhouettes. This one features a wraparound bodice with pretty cap sleeves and falls to a voluminous, A-line tiered skirt. It turns to reveal an open back, secured with double tie fastenings that can be styled into pretty bows. Wear yours with chunky sandals.
