I always used to be a boyshorts girl. I've graduated.
My friend Andrea (and pretty much all of my other girlfriends) introduced me to Hanky Panky undies, and I truly won't wear anything else now!
The softest, most comfortable, stretchy thongs out there.
They ARE a bit pricey, but totally worth it. (And tip: You can get 'em way cheaper at Neiman Marcus Last Call at Great Lakes Crossing!)
