Campus washing machines are great for three months' worth of sweaty stuff, but when it comes to delicates, those high-efficiency, industrial-grade washers and dryers are just too tough for your darling unmentionables. So, unless you're willing to hand-wash your thongs in the common room sink, you're stuck with heavy-duty cotton, right? Wrong!Thanks to the wonders of machine-made lace, polyester and other modern miracles, there's plenty of after-hours gear that's a lot tougher than it looks. Never again do you have to sacrifice sexy in favor of – erm – sturdier down-under options. These tiny underthings have all the cuteness of your hand washables, but with the endurance of your grandmother's bloomers!
