When summer is done and the time comes to trade in those tropical punch colored nail lacquers for something more appropriate for cooler temps, consider the new Swiss Collection from OPI. Inspired by the European country’s majestic beauty (think snow-capped mountains and shimmering lakes) and political objectivity (the “neutral” color palette promises to offend no one), the lineup of timeless basics, rich jewel tones and moody metallics will no doubt complement your entire fall wardrobe. Three standouts to try: Ski Till We Drop, a sophisticated grey-green-blue; From A to Z-urich, a versatile ruby hue; Lucerne-tainly Look Marvelous, a very posh pewter.
