Now, on the heels of a mega-successful Target collaboration and the launch of their first book, The Career Code ($12; amazon.com), Kerr and Power are sharing tricks for landing (and nailing) job interviews. First up? Mastering the no-fail office outfit. "For days when you have a job interview or a big meeting, wear a favorite outfit that you already own rather than buying something new, so that you know you'll feel comfortable," says Kerr. Adds Power, “You don’t want to be pulling at yourself or constantly adjusting, so this will ensure that you look and feel confident.” Here, the duo shares the go-to pieces. Printed Dress "Depending on the culture of the place, you can go conservative with a subtle print or show off your personality a bit with more color and a bold pattern," says Kerr.
