Would be this Japanese bra, that allegedly only opens when the wearer falls in love. Criticizing this is a bit like shooting fish in a barrel. From the basic idea, through the technology to the cultural subtext around female sexuality, it’s incredibly stupid. Perhaps they should instead focus on creating male underwear that only comes off when the nearest woman actually wants it to. That would have both social value and a ready market amongst the chastity play fans.
