Layering is how women dress now: a thermal under a tank top over a T-shirt. The best place to acquire a full complement of spring necessities is at this quaint, girlie shop filled with cool up-and-comers like J Brand, Ulla Johnson, and Yumi Kim. There are also cashmere cardigans and lace-trimmed tops, but focus on the basic tees and tanks from Saint Grace. They’re razor-thin, supersoft, the perfect length to peek out underneath your sweater, and fine enough to wear under anything—even another Saint Grace shirt. The basic black or white is a given, but they also come in cheery colors and in a variety of cuts (from $30).
