Via linker SayUncle, Anthroblogogy, and then originally Girls <3 Guns, I discovered this new holster design made especially for women, from a company called "Naturally Concealed."
It's an underboob holster. (which I guess could technically be an undermoob holster, too - for the right type of man.)
You wear it like this:
And conceal it like this:
Cute, right? Definitely a clever way to use the feminine shape and the resulting fabric drape to conceal a handgun. (although we less amply endowed ladies might need a baggier shirt and perhaps a smaller pistol) This design would probably also help with your posture - you slouch while wearing that thing and there'll be pistol grip jabbing into your xiphoid process. A great reminder to sit up straight, huh?
I'm definitely intrigued by this carry method but for the life of me I can't figure out how you'd get your pistol out in a hurry. Pull your shirt up from the waist to about your collarbones to assure a clear draw? Or dramatically rip your shirt open, buttons popping and flying everywhere? And do you match your bra to your panties or your holster?
