The humble bra has been confounding clumsy men's bumbling advances for decades.
And now a Japanese lingerie company has made it even more difficult for the wandering hand of a drunken bloke to get to the goodies.
As part of its 10th year anniversary campaign, Ravijour has developed a 'smart bra' that only pings open when it senses that its wearer is in love. One for the traditionalists then.
So as well as protecting the wearer against the nightclub groper, women will also have to wave goodbye to the one night stand.
The smart bra monitors the heart rate of its wearer and sends the information via Bluetooth to a smartphone app - it would then pop open automatically once it is satisfied that your heart rates says that you are in love.
Named the true love tester, this high-tech bra is not yet available for sale.
However, one could win a chance to try it out after buying ¥5,000 worth of lingerie from the brand.
