Now, A Bra that unhooks for 'True love'

Japanese lingerie brand has launched a bra that will only unhook by the woman's "true love".

The bra, designed by manufacturer Ravijour, monitors woman's heart-rate, hormones and nervous system through a mobile phone app and makes sure that the guy unhooking it is "Mr. Right", the Daily Star reported.

The bra, which unhooks only after sensing an instant boost of love-filled excitement, sends the body's functions as a signal to the app, which then determines if the " true love rate" is enough to unclasp it.

According to Ravijour, the bra will not continually burst open, as the app has the knowledge to recognize different situations and can pick apart a rising heart rate from jogging from romance.

The lingerie brand also said that the bra can come in handy for women to save themselves from unwanted sexual advances.
