Heidi Klum wears Astor’s Perfect Stay Gel Shine Polish in Opal O Mine. The formula isn’t available in the U.S., but you can get a similar look with Clinique’s A Different Nail Enamel ($13) in Made of Steel!
Sparkling Nail Powders Set ($48) 1. Work with one nail at a time, adding glitter to a thick, just-applied coat of clear polish. 2. For a light application, hold the glitter above your nail and tap the cap gently; for more drama tap the glitter directly onto the wet polish. 3. Most importantly, don’t forget the topcoat! A heavy coat will keep your glitter in place, and two coats will give the heaviest glitter a smooth finish.
