Underwiring.
If men's underpants periodically turned on them and tried to stab them through the testicles - you BET science would have worked on a solution by now.
But bras... nope! Time and time again we have to weigh up the monoboob issue versus the delightful realization that by 10am your underwear has decided it wants you dead and you're destined to spend the remainder of the day trying to discreetly shove the underwiring back in where it belongs before it all pops up, out of your shirt neck and tries to make a bid for freedom up your left nostril.
The stuff is washing machine destroying work of Satan and science should come up with a solution that lifts, separates and doesn't want you dead.
Anyone think I'm NOT being unreasonable here?!
