An Underwire Bra

The wire in your lingerie can trigger sensitive airport metal detectors to go off. Opt for a bra that offers support but doesn't make you susceptible to a pat-down inspection. For a light lift, we like the metal-free Bra-llelujah All-Hosiery Comfort Bra by Spanx—it won't get you stopped at security or dig into your back and shoulders during a long flight.
