This is a bra designed by Japanese lingerie manufacturer Ravijou that has a front clasp that will only release when "true love" is detected via a special heart-rate monitor and magical algorithms. But what if you're going to bed alone and just don't want to sleep in your bra?!
The bra comprises of a sensor which monitors your heart rate and other vitals, the data is constantly transmitted via Bluetooth to a mobile phone which processes the data using a special app and measures the heart rate elevation using special algorithms and preset data and it is only when your heart has truly found that special someone would it beat in a way that the app would recognize and wirelessly unhook the bra.
Ladies can relax as not any changes in heart rates will unhook the bra as the experts at Ravijour say it is only when a woman falls in true love does she get excited enough for the Adrenal Medulla to secrete Catecholamine which affects the autonomic nerve and increases the heart rate which is detected by the sensor and processed by the specially developed iOS app.
I doubt it really works that well. Except around me. Around me bras would be popping off left and right, but I can't have that because then what would my girlfriend think? Probably about slapping me for looking at another woman's boobs. *smack* Jesus -- I thought she was hatching a chestburster, honest!
Keep going for a weird video about the bra that made me feel uncomfortable.
