Tonight, we glitter.

Grown-up glitter is exactly that. Think purposefully placed: a sprinkling on the eye’s outer corner (Burberry Prorsum), a gold wash over the lids (Saint Laurent) or a fine line under the brow (Giambattista Valli). Why glitter? Why not? “Every girl deserves a silver lining—that’s my thought,” Val Garland, makeup artist for M.A.C Cosmetics, told us backstage at Giambattista Valli in Paris, referring to the sparkling metallic shade she was using. Tip: Before putting glitter on, apply a thick layer of powder—Garland used Ben Nye Neutral Set Colourless Powder ($11.50)—anywhere it might fall. When you’re done applying, brush off the powder; any errant glitter will go with it.
