Founded by sister duo Stephanie and Samantha in 2013, British label Pretty Lavish has quickly become beloved for its occasion-ready attire and the latest iteration of its popular Piper dress makes it easy to understand why. Whipped up from lightweight crepe and shaped to a sleeveless silhouette, it's topped with a V-neckline that falls into flowing ruffles, guaranteeing some satisfying sway when you hit the dancefloor. Accessorize with Charlotte Olympia flats and matching jewellery.
