YSL La Laque Couture Tie & Dye #2 in Pop Coat, $25, bloomingdales.com


The purpose of this gorgeous, glamorous parfait-of-a-nail-polish shade is beauty and silliness. It leaves a chic sheer pink on your nails, but the joy of it is sitting by a pool with a stack of magazines, something cool to drink and nothing to do but dab at your toes with the brush from this, the prettiest nail polish ever devised.
