Swirl a blush brush like the #24 Stila Double-Sided Illuminating Powder Brush ($50) in a matte brown bronzer. Lucero used Stila Sun Bronzer in Shade 2 ($28). "The brown tone of this bronzer is perfect because it's not too orange- or red-based," said Lucero. "And the matte finish is important because it looks like the real shading of your skin as opposed to a bling-y, shimmery one, so this looks more natural."
