NARS Risky Business is a moderately warm-toned, medium copper with a sparkle finish. It is a permanent lipgloss that retails for $26.00 and contains 0.18 oz.
Risky Business is described as a "warm raspberry." It's a muted, coppery-red with pink and white shimmer. It had semi-sheer pigmentation, and it noticeably darkened the natural lip color and added a lot of shimmer. The application was mostly even, though I could slightly feel the texture of the shimmer. The color lasted for three and a half hours on me. MAC Flash of Flesh (LE, $15.00) is lighter. Dior Ambre Lumiere (227) (P, $29.50) is darker, warmer. Chanel Daydream (P, $29.50) is redder.
