After questioning about politically correctness, I found two interesting items on sale in Japan and confirm the saying "if you don't find it in Japan, it certainly simply does not exist".  

The first one called "Shotguard" (17 USD) is a pervert-proof, IR (infrared) blocking panties as apparently school girls wearing short skirt school uniform as well as athletes are facing risks to have their undies photographed by perverts using night vision camera (sic!).

At the same time, another Japanese company launches what could certainly be considered as the ultimate geek's dream: "The USB Keyboard Bra" (130 USD).

Astonishing Japan isn't it ?
