So if one were taking a short trip to the USA what is to stop one from wearing 3 shirts, two pair of pants a couple of pair of socks and of course a couple of pairs of underwear onto the plane, you could then go into the washroom, don't stay too long, and take off all but one of the shirts, pants, underware and socks and go sit down. Wonder if security could stop you from doing this and demand you "disrobe" adn leave them at a pile at the gate.
