One national nail salon chain claims it has a faster, cheaper way to get a tippety-top perfect ten. Dashing Diva's Virtual Nails system simply glues clear, full-cover plastic nails over your natural ones. The plastic nails are amazingly thin and come in 160 sizes, so you can get a perfect fit for your nail bed. Best of all, the process doesn't involve filing the surface of your own nails. We sent a staffer to try them out, and she was thrilled with the results. A full set runs only $26, and the nails look incredibly natural. Too good to be true? Kind of. The salon says the nails should last two weeks, but they began popping off after five days. ("And I'm the opposite of active," says our tester.) The bottom line: Consider them an option if you want to enjoy a few days of gorgeous nails.
