L.A.-based nail stylist Luca Harino spent a day and a half crafting Willow Smith's spectacular press-on nails for her December issue photo shoot, which comprise silver-painted teddy bear charms, satin flowers, clusters of studs, and the letter W suspended on a chain. "We wanted them somewhat simple and classy," says Harino. "But she's 10. So we also wanted them to be fun."
