We've got the 2014 equivalent of a CHASTITY BELT to tell you about today. Um . . . thanks, technology?

A company in Japan has created a new BRA that only opens when you're around "true love." So, no more whipping off your bra for any smooth-talking guy with a cool El Camino and some Drakkar Noir . . . there's gotta be love.

The bra clasp is in the front, and it's fastened with a special sensor that's Bluetooth enabled, and works with an app on your phone.

The creators have figured out how a woman's heart rate changes when she's around someone she loves . . . so if the app detects that heart rate pattern, someone can open the bra.

It's a funny idea, but it's definitely not perfect . . . because, you know, there has to be a way to take it off when the woman wants to take a shower or go to sleep and her true love doesn't happen to be hanging around.

There's no word on when it'll go on sale in Japan or whether it could hit the U.S.
