Katharine McPhee has been quite the stylish stunner as of late. While promoting her new show Smash on Late Night With Jimmy Fallon in NYC, the actress and singer showed us that mixing pink, orange, and green doesn't have to lend silly results. On the contrary, the blend is super sophisticated and fashion forward. Katharine started with a deep pink silk blouse, which she tucked into an orange slit skirt, and finished off with green silk Charlotte Olympia pumps — here's a pair that's less expensive but equally fab. This outfit would look great everywhere from the office — sans slit — to a soiree. You can use the color combo with different silhouettes, like an orange blouse tucked into pink trousers with green sandals, or a green sweater with a pink skirt and orange pumps. Just play around until you've found the perfect version for you.
