EXCLUSIVE AT NET-A-PORTER. Envelope1976's mission is to design seasonless clothing that lasts. This 'Diaz' maxi dress makes a beautiful city wedding option that can also be worn after the big day with a turtleneck and flats. It's cut from crepe de chine that falls loosely over the body and has slim ties for a tighter fit. The draped cowl neck and dipped back call for a self-adhesive bra.
