EXCLUSIVE AT NET-A-PORTER. Founder Heidi Middleton says she imagines ARTCLUB's designs being worn everywhere from the grocery store to the Art Biennale in Venice, which is why they're so easy to dress up and down. Cut from silk-dupioni, this gold 'Aster' dress has a voluminous one-shoulder neckline and plush velvet ties that wrap around the narrowest part of your waist. Wear it with sneakers or sandals, depending on the occasion.
