Fashion Weeks — from New York to Paris — are where new trends are born for clothes, as well as for the makeup and accessories that complete designers’ visions. We spent time backstage during New York Fashion Week, checking out what’s coming up on the makeup front, when CND (that’s Creative Nail Design) invited us to see what their amazing nail stylists, Roxanne Valinoti, Angi Wingle, and Kristina Estrabrooks, created for 20 designers with the endlessly versatile Colour & Effects line. Click through for eight wow-worthy sets of digits, and tell us whether you use your nails as a canvas for daring looks or if you keep it simple with pink or red polish.
