Emily Giffin, 40
Where We Belong (St. Martin's), a novel about a TV producer whose carefully constructed life is shaken when the now-teenage daughter she gave up for adoption appears on her Manhattan doorstep.
"I shop once a season and I try to buy good pieces that I know won't go out of style for years and years," says Atlanta-based Giffin, whose first book, Something Borrowed, was made into a film starring Kate Hudson in 2011. "But somehow I always find an excuse for new shoes!"
A Michael Kors navy cardigan with gold buttons. "It was originally $800, but I got it for half price," says Giffin. "I've worn it more than 400 times over the years, as it's my go-to for flights. So that's less than $1 per wear, and it still looks new."
Her Makeup Story
The conflict: "I've just started wearing makeup regularly in the past couple of years. I'd love to play up my eyes more, but I'm intimidated by all eye makeup beyond mascara."
The denouement: Lining Giffin's blue-green eyes in a deep eggplant color makes them sparkle—and it's a simple three-step process: Drag a skinny liner brush through the shadow, then trace it along the upper lashline; use a Q-tip to smudge the color up and out.
