Meet the new must-have button-downs, which add a touch of chic intrigue to that timeless and endlessly versatile wardrobe staple. Tory Sport’s stretch poplin shirt (right), for example, is updated with rib-knit cuffs and mesh side panels for breathability while Tory’s poplin button-down, from the limited-edition Paris Collection, is a more feminine alternative to that tomboy take: it comes with a detachable collar covered in beautiful dyed plumes. Consider these your same beloved shirt classic with a bit of — how do you say — je ne sais quoi.
