You may blame bad luck when you step through an airport scanner and suddenly hear an officer ask you to move aside, but your clothes could be part of the problem. Certain fabrics, accessories, bulky garments, and even excessive perspiration can create anomalies that lead to additional screening. That does not mean TSA considers your outfit suspicious or that wearing a particular item automatically guarantees a pat-down. Still, choosing a simpler airport security outfit can reduce avoidable complications and potentially make your trip through the checkpoint smoother.
