Tights or Leggings
"Leggings and tights are your best friend," says Nasser. "Wear them under your dresses or your flowy, summer tunic-style tops." She recommends choosing darkly colored tights, stockings and leggings, as actress and singer Jennifer Damiano does here. Also look for interesting textures, such as ribbing or chunky knits, which really lend themselves to fall.
