If you're irresistibly drawn to classic Summer silhouettes à la country-inspired plaids and crisp LWDs, look no further than Katie Holmes for a double dose of Americana inspiration. The brunette beauty punched up her NYC weekend warrior status just by sporting two timeless ensembles in two equally effortless ways. Her first look was an exercise in juxtaposed textures: a silky white chemise topped with a nautical red-striped t-shirt. Meanwhile, her second outfit, comprising a knotted gingham blouse with a fresh white circle skirt, was reminiscent of BrigitteBardot's retro bombshell style. The key to her styling success? Pairing clean Summer-perfect prints with sexier separates. Be it a soft vintage dress layered with stripes or a breezy checkered top anchored with a leggy miniskirt complement, it's all about highlighting clean lines and no-fail pieces.
