Known for his clinging, sexed-up knitwear, Mark Fast took a more refined approach this season and channeled Thirties glamour. Evening gowns fit for a screen goddess came in cream-colored loose weaves while gold flapper dresses had tassel fringe. The designer continued to speak to his hard-core fans with plenty of thigh-skimming minidresses in his spring lineup. But he still needs to work on the wearability of some of his pieces as some added unnecessary (and certainly unwanted) bulk.
