I confess: I'm into gimmicks -- they're fun! My latest delight is In the Mood color-changing nail polish. My astrology sign is Gemini, which is known for constantly switching temperaments, so I keep this polish on its toes. Right now, I'm wearing "Flirty" on my fingers, and it goes from a bright pink to a glimmery white when my mood shifts. (Okay, it's actually temperature-related, but can we just suspend disbelief for a moment?)
Either way, I like having nails that go from ballet pale to Pepto pink throughout the course of the day. Try out one of six colors ($8 each) and get a rainbow of shades in one bottle!
