Once just a single-night charity event dedicated to a fashion staple, the Little Black Dress party has grown into a four-week tour of three cities. In a Project Runway-worthy twist, the organization challenges upcoming designers to create their own versions of the little black dress. Tonight's reception heralds the installation of an LBD pop-up boutique within the Sunset and celebrates the opening of an exhibition of Biago Black's guilty-pleasure portraits that take inspiration from contemporary fashion icons. Other events scheduled during the pop-up's run include "Canvas and Couture" on Wednesday and "Vino and Vinyasa" on Friday; the latter is a yoga class/wine tasting that only Angelenos could dream up.
