If you need cute, conversation piece nails in a hurry, these Kiss Pink Color Change Sticker Nails in Belle ($5) fit the bill. While they're actually meant for kids (as the whimsical packaging suggests), because they're cut down to a reasonable length and size, they'll also work for smaller adult hands. Tip: as an added measure to help them stay better, try brushing nail glue on your nails before applying.
Did I mention they change color? The base shade goes from white to pink when exposed to sunlight, and the multichrome polka-dot pattern on top is equally attention grabbing. Everyone who has noticed them has thought they were both expensive and all kinds of trendy. They hit the season's nail art craze on the dot.
