SPECIAL MENTION: It can be hard for women to find professional clothes that fit properly, even when they're looking for a basic black dress. Enter the Alpha ($195), a one-style-fits-all shift dress that comes in 99 different microsizes. The startup behind the Alpha, Laws of Motion, has done away with the fashion industry's traditional sizing model in favor of a system based on simple questions that account for variations in body shape, including torso length and bust width. —Megan McCluskey
