Guerlain La Petite Robe Noire So Crazy! Perfumed Shimmer Powder ($89.00 for 0.61 oz.) is a shimmering, pale pink powder scented with a sweet cherries and creamy almond. It’s a decadent, luxurious vanity treat–by no means a must-have, but it’s a nice-to-have if you go out and dress in little black dresses. The way the shimmer dances in the light is exquisite–really–and it dances, glimmers, and sparkles all at once and looks quite lovely on the body (shoulders, decolletage, legs). The shimmer is like micro-sparkle; larger than shimmer, smaller than sparkle and glitter. On the face, I think it can be too over-the-top unless you love sparkle, but it’s a product that works really well in hair, on arms, shoulders, legs, and so on.
