Deborah Lippmann Layer Cake Set
Layering is big in fashion, but now it's finding its way into manicures! This set of three nail lacquers — a swirling lavender iridescent called Wicked Game, the glittery Happy Birthday, and an aubergine Dark Side of the Moon — can be mixed, matched, and layered to create a ton of looks, or worn solo. $25 at Nordstrom.
