Japanese lingerie company Ravijour is currently working on designing a bra that only unhooks if the wearer is "in love." 

Brand researchers have come up with a way to quantify such a feeling - according to Ravijour designers, true love happens during the secretion of a substance called catecholamine, which produces an "instant boost in excitement." Once a woman feels that spike, the bra automatically busts open like a post-wooing prize. But if said lady isn't having your thirsty barside pick-up lines, the hosiery remains locked.

Ravijour hasn't come up with an official product just yet, but if this effort pans out, it's curtains for some - for others, it's an opportunity to dust off that guide to chivalry and get on a 1-800-FLOWERS mailing list.
