The skinny on nails: Au naturel or poser pink? Out. Long and ridiculously plastic? Out. Dark but-not-scary-goth? In. Short but not chiseled with your teeth? In. I love these colors for fall (start with a base coat to avoid unsightly stains): NYX Nails in black and Orly Moonlit Madness, and when you’re ready for a change, check out MAC’s easy travel-friendly manicure wipes. Handy polish remover in little cloths. $8.50 for a pack of 10.
