Best Bet: Rotko Dress

Scandinavian label Won Hundred is known for cleanly designed clothes with thoughtful details, like subtle seams and pleats. The brand's lower-priced spinoff line, WH100, follows the same design philosophy, offering easy, arty basics like this abstract-print Rotko dress. The viscose fabric is soft and lightweight, while the drawstring waist and pleating work with various body types. (The waist also has belt loops, if you prefer to cinch it.)  The slim keyhole back lends an understated allure.
