A sweeping maxi dress offers just the right amount of romantic drama, which is why pieces like Ulla Johnson's 'Rabia' style are wardrobe heroes for Fall '21. Made from tiered swathes of silk-chiffon, it's detailed with ruffled trims and ruching through the bodice. The squared neckline is framed by a halterneck strap and it's decorated with an abstract ikat print.
