See lessemf.com - The Copper Polyester Taffeta would be completely opaque to the MM scanners. Their Stretch Conductive Fabric PN# 251, would work well and make comfortable undergarments. Maybe somebody will start a business with some science behind it.
While that's true, leather or metallic fabric would appear as an anomaly on the nude-o-scope display and almost certainly would win the passenger a real strip search after the virtual strip search. (I'm not sure that leather would work as well as people think, but nevermind.)
A question has been posed many times in this forum along the lines of "what can I wear that protects my modesty but won't show up on the nude-o-scope?" The answer is no different, really, for the nude-o-scope than for visible light. You might as well ask "What can I wear on the beach that would preserve my privacy but not look like I'm wearing anything even on close inspection?" Either the clothing is transparent (to x-ray, MMW or light) or it's going to be visible (to x-ray, MMW or light).
